; port I/O routines
; These routines access the ports configured in TmsPort.
; These memory locations can be set at runtime to support different hardware
; configurations from the same binary. TmsProbe automatically detects the
; TMS9918A on common ports.
; The TMS9918A RAM must not be accessed more than once every 8 us or display
; corruption may occur. During vblank and with the display disabled,
; accesses can be 2 us apart, but we will always use 8 us minimum delay.
; TmsRamIn/TmsRamOut include a configurable delay loop, which waits for the
; configured iterations between VRAM writes to work properly with faster CPUs
; Minimum time to execute each procedure call:
; Z80: 88 cycles, 8.8 us @ 10 MHz
; Z180: 80 cycles, 8.64 us @ 9.216 MHz, 4.32 us @ 18.432, 2.16 us @ 36.864
;
; Additional delay per djnz iteration:
; Z80: 8 cycles * (iterations - 1)
; 0.8 us @ 10 MHz
; Z180: 7 cycles * (iterations - 1)
; 0.756 us @ 9.216 MHz, 0.378 us @ 18.432, 0.189 us @ 36.864
; Delay loop iterations required for different CPU speeds:
; Z80 @ 10 MHz or less: 1
; Z180 @ 9.216 MHz or less: 1
; Z180 @ 18.432 MHz: 10
