For this * reason, we reserve some low memory for the screen. * * Screen memory range is $0500-$08FF (1K). Of that, 40*24 (960) bytes * are for the screen buffer and the remaining 64 bytes are for the * ANTIC's Display List G.Cols equ 40 G.Rows equ 24 G.ScrStart equ $0500 G.ScrEnd equ G.ScrStart+(G.Cols*G.Rows) * The Character Set must be aligned to a 4K address. We can really only * guarnatee that in the Krn module, which is always at the end of RAM. So * for now, the character set is located at $F800 G.CharSetAddr equ $F800 * POKEY requires shadow registers. We allocate them in the kernel's DP * (Yes, we are stealing an existing variable that is so old it should be * removed from os9defs) D.IRQENShdw equ $02 ; was D.WDBtDr D.SKCTLShdw equ $03 ; was D.SWPage * The clock interrupt is driven by the unmaskable NMI. Therefore, * the rbdw3 driver uses the DWIOSEMA flag in the D.ATARIFLAGS field as * a signal, setting it before doing an DW operation and clearing it after. * The clock ISR checks if this flag is set, and, if so, defers the OP_TIME * command to the server.
