Updated the ; 10ms delay to be a little longer. Renamed the Macsbug continue ; var to PDMDebugCont. for consistancy. ; 10/7/92 GS Increase size of Cuda manager globals so that support for ; calling the resume procedure associated with power messages can ; be accessed externally. ; Added equates for debugger continue (Power Message Support). ; Added equates for asynchronous IIC traffic. ; 9/18/92 GS Added Time out equates, and added a new Shutdown selector for ; the Macsbug Continue state. ; 6/26/92 GS (RBM) Comment now says the WrDFAC is always DFAC mode. ; Eliminated SetDFACmode and replaced it with RdWrIIC. RdWrIIC is ; always I squared C mode. Expanded Egret parameter blocks so ; that the Cuda manager can have room for extensible features… ; Added equate for hardware based delay in SyncAck cycle (see ; CudaInit). ; 5/22/92 RB Updated for new values used for Cuda in Pandora. ; ; SuperMario Change History: ; ; <11> 10/28/91 SAM/KSM Rolled in Regatta file. ; ; Regatta Change History: ; ; <3> 6/14/91 SAM (bg) Made this file look like the one in TERROR. ; <1> 6/12/91 SAM Split off from 7.0 GM sources. ; ; 7.0 Change History: ; ; <10> 1/30/91 gbm sab, #38: Change the ‘already including this file’ variable to ; all uppercase (for security reasons) ; <9> 5/8/90 GA Added Retry Count and Timeout count for SendEgretCmd new ; RetryCount and Timeout support in SendPtype. ; <7> 4/25/90 GA Added equates needed in EgretMgr to fix DFAC bug and Error ; reporting bug. ; <6> 4/10/90 GA Added equates to support the error checking code in EgretMgr.a ; <5> 4/2/90 GA Changing the ElsieDFAC back to $57 AGAIN!!!. The hardware people ; should make up their minds! ; <4> 3/30/90 GA Added equates for EricksonDFAC & ElsieDFAC ; <3> 2/28/90 GMR Modified to match new EgretMgr.a ; <2> 2/3/90 GA first checked in ; <1> 2/3/90 GA first checked in ;
