|

-- Create Date: 12:37:11 05/07/2011
|
||||
-- Design Name: SPI65B
|
||||
-- Module Name: SPI6502B - Behavioral
|
||||
-- Project Name: CS/A NETUSB 2.0
|
||||
-- Target Devices: CS/A NETUSB 2.0
|
||||
-- Tool versions:
|
||||
-- Description: An SPI interface for 6502-based computers (or compatible).
|
||||
-- modelled after the SPI65 interface by Daryl Rictor
|
||||
-- (see http://sbc.rictor.org/io/65spi.html )
|
||||
-- This implementation here, however, is a complete reimplementation
|
||||
-- as the ABEL language of the original implementation is not supported
|
||||
-- by ISE anymore.
|
||||
-- Also I added the interrupt input handling, replacing four of the
|
||||
-- original SPI select outputs with four interrupt inputs
|
||||
-- Also folded out the single MISO input into one input for each of the
|
||||
-- four supported devices, reducing external parts count again by one.
|
||||

|
||||
-- Dependencies:
|
||||
--
|
||||
-- Revision:
|
||||
-- Revision 0.01 - File Created
|
||||
-- Revision 0.02 - removed spiclk and replaced with clksrc and clkcnt_is_zero combination,
|
||||
-- to drive up SPI clock to half of input clock (and not one fourth only as before)
|
||||
-- unfortunately that costed one divisor bit to fit into the CPLD
|
||||
-- Additional Comments:
|
||||
-- Spi controller for 6502 systems
|
||||
-- based on a design by A. Fachat
