+; 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
