Digital I/O (Digital Input/Output) pins are provided for custom system design.
This appendix provides definitions and its default setting for the Digital I/O
pins in the nROK 500. The pin definition is shown in the following table:

IO base address : 800h

Bit0 : GPO20
Bit1 : GPO21
Bit2 : GPO22
Bit3 : GPO23
Bit4 : GPI 24
Bit5 : GPI 25
Bit6 : GPI 26
Bit7 : GPI 27

1. Read/Write GPIO data by I/O port 801h
