1. Overview
The chip has 8 ports for multi-functional input/out pins. They are shown below:
Port A(PA): 18 input/output port
Port B(PB): 24 input/output port
Port C(PC): 25 input/output port
Port D(PD): 28 input/output port
Port E(PE) : 12 input/output port
Port F(PF) : 6 input/output port
Port G(PG) : 12 input/output port
Port H(PH) : 28 input/output port
Port I(PI) : 22 input/output port
Port S(PS) : 84 input/output port for DRAM controller
For various system configurations, these ports can be easily configured by software. All these
ports (except PS) can be configured as GPIO if multiplexed functions not used. 32 external PIO
interrupt sources are supported and interrupt mode can be configured by software.
