VCC1

Applies the reference voltage for the A-D converter and D-A converter.

Analog input pins for the A-D converter

This is an A-D trigger input pin.

This is the extended analog input pin for the A-D converter, and is the output

in external op-amp connection mode.

This is the extended analog input pin for the A-D converter.

This is the Input pin for the D-A converter

8-bit I/O ports in CMOS, having a direction register to select an input or

output.

Each pin is set as an input port or output port. An input port can be set for a

pull-up or for no pull-up in 4-bit unit by program.

I/O ports having equivalent functions to P0.

(except P7_0 and P7_1 for the N-channel open drain output.)

_______

Input pin for the NMI interrupt.

Pin states can be read by the P8_5 bit in the P8 register.

I/O

I : Input

O : Output

I/O : Input and output

NOTES:

1. There is no external connections for port P1, P4_4 to P4_7, P7_2 to P7_5 and P9_1 in 80-pin version.

Set the direction bits in these ports to “1” (input mode), and set the output data to “0” (“L”) using the program.
