Applies the reference voltage for the A/D 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.
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_0 and
P7_1 for the N-channel open drain output.)
I/O ports having equivalent functions to P0.
Input pin for the NMI interrupt. Pin states can be read by the P8_5 bit
in the P8 register.
