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.
This is the input pin for the CAN module.
This is the output pin 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.
