I/O port P5

I/O port P7

Output port P9

P5 is an 8-bit I/O port with the same function

as port P0 and can be programmed as I/O

pins for timers A0–A3.

P7 is an 8-bit I/O port with the same function

as port P0 and can be programmed as analog

input pins for the A-D converter. P76 and P77

can be programmed as I/O pins (XCOUT, XCIN)

for the sub-clock (32 kHz) oscillation circuit.

When using P76 and P77 as pins XCOUT and

XCIN, connect a quartz-crystal oscillator between

them. When inputting an external clock, input

the clock from pin XCIN.

P9 is an 8-bit output-only port. After reset, P9

enters a floating state. When data is written to

the port P9 register, P9 starts outputting (Note).

P90–P93 also function as UART2’s I/O pins.

P10 is an 8-bit I/O port with the same function

as port P0. Pins 104–107 can be programmed

as input pins (KI0–KI3) for the key input interrupt.

Leave these pins open.
