Description
I VCC1 Applies the reference voltage for the A/D converter and D/A
converter.
I VCC1 Analog input pins for the A/D converter.
I VCC1 This is an A/D trigger input pin.
I/O VCC1 This is the extended analog input pin for the A/D converter, and is
the output in external op-amp connection mode.
I VCC1 This is the extended analog input pin for the A/D converter.
O VCC1 This is the output pin for the D/A converter.
I/O VCC1 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 VCC1 I/O ports having equivalent functions to P0.
I/O VCC1 I/O ports having equivalent functions to P0.
(however, output of P7_0 and P7_1 for the N-channel open drain
output.)
I _{VCC1 Input pin for the NMI interrupt.}
Pin states can be read by the P8_5 bit in the P8 register.

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” (output mode), and set the output data to “0” (“L”) using the program.
