These two registers select GP1 I/O base address [0x100:0xFFF] on 1 byte boundary.
These two registers select GP14 alternate function Primary I/O base address [0x100:0xFFE] on 2
byte boundary; they are available as you set GP14 to be an alternate function (General
Purpose Address Decode).
These two registers select GP15 alternate function Primary I/O base address [0x100:0xFFF] on 1
byte boundary; they are available as you set GP15 to be an alternate function (General
Purpose Write Decode).
