// File: HardwarePrivateEqu.r (generated from HardwarePrivateEqu.a)
//
// Contains: Macintosh assembly equates THAT ARE NOT TO BE RELEASED TO THE WORLD.
//
// Copyright: © 1990-1993 by Apple Computer, Inc., all rights reserved.
//
// Change History (most recent first):
//
// <SM14+> 8/4/93 JDR private sound defines are in SoundPrivate.a
// <SM14> 6/9/93 kc Roll in Ludwig.
// <LW2> 2/24/93 chp Added equates for the PSC wait/request multiplexer control bits
// in VIA1.
// <SM13> 8/17/92 CCH Bumped HeapStart to $2800.
// <SM12> 8/7/92 JDB Changed Singer control register to have 0 for the output
// attenuation and 5 for the input gain.
// <SM11> 07-14-92 jmp (ag,H24) Change the name of a bit from PontiSndExtMic to
// PontiSndIntMic
// (jmp,H23) Added some additional DAFB equates for the WombatDAFB
// code.
// (BG,H22) Added one more djMEMC-related symbolic definition
// (dj_MaxBanks).
// <SM10> 6/21/92 ejb Adding bit field definitions for dspOverrun register in PSC.
// <SM9> 6/21/92 RB Adding runtime support for EVT1 and EVT2 Cyclones. Defined
// temporary equates for the EVT1 Cyclone units.
// <SM8> 6/18/92 KW (BG,H21) Added djMEMC memory controller equates for Wombat and
// WLCD.
// (jmp,H20) Wombat has a different dot-clock chip than
// Spike/Eclipse/Zydeco, so I added an equate to reflect this.
// <SM7> 6/18/92 RB Added equates for the new EVT2 (final offsets) of the VIA2 on
// Cyclone. The old values are still supported under the
// conditional forEVT1. These should be deleted once everyone moves
// to EVT2 boards. Did the same with MUNIBase as well.
// <SM6> 6/4/92 KW (fau,P18) Added and equate for Civic_VidInDble to support Civic
// II.
// <SM5> 5/25/92 RB Removed a forCyclone conditional. This should be the last one
// left. Renamed MSCBank1Enable to MSCBank8M.
// <SM4> 5/21/92 RB Making changes for Cyclone. Some comments may be duplicated due
// to the Pandora/Terror history. <P17> 5/13/92 KW (ag,H18) Added
// Ponti Definitions. (BG,H17) Added symbol v2MicCtl to the VIA2
// bit definitions. This is a microphone control bit that is
// defined for Wombat. Also updated some comments from Eclipse and
// Zydeco to the appropriate Quadra names. <P16> 4/16/92 KW (SWC,
// H16) Set bufWorldSize to 8K so Macsbug won't load into the
// middle of DBLite's sound buffer and get trashed when a sound is
// played. <P15> 03/24/92 jmp Renamed one of the MMC registers to
// something more appropriate (i.e., MMC_Interlace to
// MMC_ClockSelect). <P14> 03/22/92 jmp Put back <P12>. <P13>
// 3/19/92 FU Rolled back changes in <P12>. <P12> 3/18/92 FU
// (SWC,H15) Added SCSI DiskMode bit definitions for Niagra to the
// VIA 1 list. <P11> 03/04/92 jmp Updated the comments and changed
// the names of some of the Civic-related equates. <P10> 02/28/92
// jmp (ejb) Turned off the DSP frame-interrupt enable bit so that
// DSP driver doesnÕt suffer frame overrun when it trys to boot the
// DSP. <P9> 02/20/92 jmp (JC,H14) Define PatchFlags in unused by
// of ROM header ($0014). Define PatchBits based on available
// features in BBSStartup. Include support for Horror based and
// Pandora (Cyclone) based ROMs. <P8> 2/19/92 chp (jmp,H13) Put a
// ÒhasSonora1Ó conditional around the Sonora video control
// register base address to reflect impending hardware changes to
// Sonora. <P7> 02/07/92 jmp (HJR,H12) Added new Niagra Equates.
// (SWC,H11) One more go-round on MSC configuration: RAM bank 1
// needs to be disabled since there's only 2MB on DBLite LC.
// (SWC,H10) Fixed the MSC configuration value: it needs to be
// setup for a minimum amount of RAM so that the sound FIFO will
// always exist in real RAM for BootBeep. (SWC,H9) Added an equate
// for the default MSC configuration register value. Also, added
// Civic and Civic-related equates for Cyclone. <P6> 2/5/92 RMP
// Added MUNI equates. <P5> 1/21/92 mal Added PSC VIA2 equates <P4>
// 1/18/92 RMP Added PSC sound equates. <P3> 1/15/92 RP Fixed
// header (sorry). <P2> 1/15/92 RP Added new VIA definition bits
// and MMC equates.
// <SM3> 5/17/92 kc Roll in Horror Changes. Comments follow:
// <H16> 4/8/92 SWC Set bufWorldSize to 8K so Macsbug won't load into the middle of
// DBLite's sound buffer and get trashed when a sound is played.
// <H15> 3/3/92 SWC Added SCSI DiskMode bit definitions for Niagra to the VIA 1
// list.
// <H14> 2/19/92 JC Define PatchFlags in unused by of ROM header ($0014). Define
// PatchBits based on available features in BBSStartup. Include
// support for Horror based and Pandora (Cyclone) based ROMs.
// <H11> 1/23/92 SWC One more go-round on MSC configuration: RAM bank 1 needs to be
// disabled since there's only 2MB on DBLite LC.
// <H10> 1/22/92 SWC Fixed the MSC configuration value: it needs to be setup for a
// minimum amount of RAM so that the sound FIFO will always exist
// in real RAM for BootBeep.
// <H9> 1/22/92 SWC Added an equate for the default MSC configuration register
// value.
// <H8> 12/20/91 JC Create common Via2/RBV offset equates and temporary redefinition
// on Sonora Specific builds to only use RBV offsets
// <H6> 12/03/91 jmp Added various (but not yet complete) SonoraAddr and
// Sonora-VDACAddr equates. Sorry to have cancelled your check-out
// swc, but we had pressing needs.
// <H5> 11/26/91 jmp Added equates for the GSC.
// <H4> 11/25/91 SAM Added Sonora specific equate for RAMSize reg.
// <H2> 8/5/91 SWC Added MSCPowerCycle, the offset to the power cycle register from
// the base of the MSC.
// <T21> 7/8/91 HJR Rename JAWSAuxWaitS to JAWSEconoMode register to reflect its new
// pupose in life.
// <T20> 5/24/91 jmp Added another VIA2, port A, bit-7 equate for Spike & Eclipse:
// v2SyncOnGreen. This bit allows us to enable & disable the
// sync-on-green signal in ACDC.
// <T19> 5/10/91 djw Add sound input select bits for Eclipse in VIA2
// <T18> 5/1/91 HJR Added in register definitions for the MSC memory controller

// <T17> 4/1/91 BG Modified the v2Keyswitch bit definition to agree with what it
// will be on DVT Eclipse.
// <T14> 3/3/91 BG Added bit definition for Eclipse Keyswitch bit in VIA2.

// <T6> 11/7/90 BG Made changes for new rev. of Orwell (2) permanent.
// <SM2> 4/22/92 RB Moved the start of the System heap in order to get some space
// for vector tables. This movement of the heap from $2000 to $2100
// is for experimentation and will need to be changed at a later
// date.
// <35> 12/31/91 RB Renamed JAWSAuxWaitS to JAWSEconoMode to reflect its real
// purpose.
// <34> 12/29/91 RB Updated some of the Terror constants.
// <33> 10/28/91 SAM/KSM Rolled in Regatta file.
//
//
// <2> 8/8/91 SAM (pdw, ag) Added some equates from HardwarePrivateEqu in
// TERROR.
// <1> 8/8/91 SAM Split off from 7.0 GM sources.
//
//
// <32> 10/1/91 JSM DonÕt use eclipseDebug.
// <31> 8/30/91 DTY Complicate matters so onMac32 stuff doesnÕt get defined for
// onMac, onMacPP, or onMacHc. (Since these arenÕt defined in
// BBSStartup anymore, this is necessary.)
// <30> 8/22/91 JSM Clean up header.
// <29> 7/24/91 MH Added conditional wrapper(s) to prevent duplication of public
// interface declarations: TimeSCSIDB
// <28> 1/30/91 gbm sab, #38: Change the Ôalready including this fileÕ variable to
// all uppercase (for security reasons)
// <27> 11/26/90 gbm (and bbm) On 7.0 (and other places eventually) HiIntMask will be

// <16> 4/4/90 HJR Clean up some build problems.
// <15> 4/4/90 MSH forrom removal.
// <14> 4/4/90 MSH Merged HardwareEqu.a back into HardwarePrivateEqu.a and
// restructured/rewrote the resultant file. This action obsoletes
// HardwareEqu.a. All future equate additions should be done to
// HardwarePrivateEqu.a only.
// <13> 3/29/90 MSH Add VIA2 labels for Waimea.
// <12> 3/22/90 JJ Force definition of onElsie=0 if onElsie is undefined.
// <11> 2/14/90 DAF Added VISA register names. Since Elsie isn't fully integrated,
// it doesn't have real feature conditional yet.
// <10> 2/9/90 BG Modified ORWELL_INIT value to reflect the parts being used on
// the Eclipse prototype.
// <9> 2/9/90 JJ Added RvExp, offset of RBV Expansion Register in Elsie.

// Welcome to the New Hardware Equates File. By following some simple procedures this file
// can keep its youthful appearance for years to come. This file is a recombination of
// HardwareEqu.a and HardwarePrivateEqu.a. Everyone should be using this file only. Please
// change any of your files that use either of the hardware equate files to use only this one.
// HardwareEqu.a will be left as an historical artifact for future generations.
//
// To help you navigate through this file use the "Mark" menu item, and please help to keep
// it current. When you add a new section, add a handy mark to find it again. Equates are
// grouped in a semi-logical way in the follwing order:
//
// Chip Offsets - Register offsets for the 'standard' Mac peripheral chips.
// Chip Offsets 2 - Register offsets for the 'non-standard' Mac peripheral chips.
// VIA1 - Register offsets and pin descriptions.
// VIA2 - Register offsets and pin descriptions.
// RBV - Register offsets and pin descriptions.
// VISA - Register offsets and pin descriptions.
// Memory Controllers - Register definitions and miscellaneous equates.
// Interrupts - Auto vector names and mask definitions.
// Miscellaneous - The "Smorgasboard" of equates.
// Old 16 Bit Equates - Machine dependent equates for Mac, MacPP, HcMac, and Mac16.

// Orwell Memory Controller Equates <5>
//---------------------------------------------------
// Orwell only has one input/output data bit. So to store or retrieve any configuration register
// information, you must read/write a succession of long-word addresses, starting at the addresses
// below, with the ONLY valid data bit being {reg}:0. Valued being read must be assembled one bit
// at a time; values being written must be loaded into the config registers 1 bit at a time. The
// new config. register values do not become active until a "latch" register address associated
// with the config. register is written.
//
// The below addresses correspond to longword addresses where bit 0 of whatever data register used to
// read/write the location will be stored. The Orwell configuration register is a 34-bit register,
// with each bit written to/read by addressing the appropriate longword offset.
//
// The configuration register can be thought of like this:
//
// +---------------------------------------------------------------------------------------------+
