2.7

Port 0 pins

Port 0 consists of a 32-bit bidirectional I/O port (only 3-bit are used in STA8088GA).

It can be either used as general purpose Input or Output port, or configured according to the

associated alternate functions.

2.8

Port 1 pins

Port 1 consists of a 32-bit bidirectional I/O port (only9-bit are used in STA8088GA).

It can be either used as general purpose Input or Output port, or configured according to the

associated alternate functions.
