Table 1.5 Pin Description (100-pin and 128-pin Versions) (2)

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.

These are the output pins for the D/A converter.

These are the input pins for the CAN module.

These are the output pins for the CAN module.

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.

(except P7_1 and P9_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.
