Functions

Port P7 is a 4-bit I/O port. P72 and P73 also function as input pins for INT3 and

INT4. According to the software setting, these pins also function as input pins for

the A-D converter.

I/O Port P8 is a 7-bit I/O port. These pins also function as I/O pins for UART0, UART1.

Output This is an output pin for CS0.

I/O Port P9 is a 6-bit I/O port. According to the software setting, P91–P93 also funtion

as chip select output pins. While DRAM space is selected, P94–P96 function as

output pins for DRAM control signals.

I/O Port P12 is a 3-bit I/O port. These pins also functions as input pins for INT0, INT1,

INT2. According to software setting, these pins also function as input pins for timers

B0–B2.

Input This pin is for a non-maskable interrupt.
