Description

P0: 8-bit Input-output port. Each bit can be assigned to be an input or an output.

AD: When an external memory is used, these pins output the lower 8 bits of the

address. These pins also input or output the data.

P1: 8-bit Input-output port. Each bit can be assigned to input or output.

A: When an external memory is used, these pins output the upper 8 bits of the

address.

P2: 8-bit Input-output port. Each bit can be assigned to input or output.

I/O RTO: Output pin for real time output

FTM10: Capture input pin or real-time output pin

P3: 8-bit Input-output port. Each bit can be assigned to input or output.
