These two registers select Game Port base address <100h : FFFh> on 1
byte boundary.
These two registers select MIDI Port base address <100h : FFEh> on 2
bytes boundary.
These bits select IRQ resource for MIDI Port.
GPIO1 I/O register
0: The respective GPIO1 PIN is programmed as an Output port
1: The respective GPIO1 PIN is programmed as an Input port.
GPIO1 Data register
For Output ports, the respective bits can be read/written and produced to
pins.
For Input ports, the respective bits can be read only from pins. Write
accesses will be ignored.
GPIO1 Inversion register
0: The respective bit and the port value are the same.
1: The respective bit and the port value are inverted. (Both Input & Output
ports)
