Function
I/O P70 to P76 are I/O ports equivalent to P0 (P70 and P71 are N
channel open-drain output).
Pins in this port also function as UART2 I/O pin, INT0 to INT2
input pins as selected by software.
I P77 is an input-only port that also functions for NMI.
I/O This is a 8-bit I/O port equivalent to P0. Pins in this port also
function as timer A4 to A7 I/O pins, INT5 input pin as selected by
software.
P90 to P97 I/O port P9
I/O This is an 8-bit I/O port equivalent to P0. Pins in this port also
function as A-D converter analog input pins as selected by
software.
P100 to P107 I/O port P10
I/O This is an 8-bit I/O port equivalent to P0. Pins in this port also
function as SEG output for LCD as selected by software.
P110 to P117 I/O port P11
I/O This is an 8-bit I/O port equivalent to P0. Pins in this port also
function as SEG output for LCD as selected by software.

I/O This is an 8-bit I/O port equivalent to P0. Pins in this port also
function as SEG output for LCD and real time port output.
I/O This is an 3-bit I/O port equivalent to P0. Pins in this port also
function as D-A converter analog output pins or start trigger for
A-D input pins.
O Pins in this port function as SEG output for LCD drive circuit.
O Pins in this port function as common output for LCD drive circuit.
Power supply input for LCD drive circuit.
