NOTES:
1. When use VCC1 > VCC2, contacts due to some points or restrictions to be checked.
2. Ports P11 to P14 in M16C/62P (100-pin version) and M16C/62PT (100-pin version) cannot be used.

VREF I VCC1 Applies the reference voltage for the A/D converter and D/A
converter.
A/D converter AN0 to AN7,
AN0_0 to
AN0_7,
AN2_0 to
AN2_7
I VCC1 Analog input pins for the A/D converter.
ADTRG
I VCC1 This is an A/D trigger input pin.
ANEX0 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.
ANEX1 I VCC1 This is the extended analog input pin for the A/D converter.
D/A converter DA0, DA1 O VCC1 This is the output pin for the D/A converter.
I/O port P0_0 to P0_7,
P1_0 to P1_7,
P2_0 to P2_7,
P3_0 to P3_7,
P4_0 to P4_7,
P5_0 to P5_7,
P12_0 to

I/O VCC2 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.
P6_0 to P6_7,
P7_0 to P7_7,
P9_0 to P9_7,
P10_0 to
P10_7,
P11_0 to
P11_7
(2)
I/O VCC1
8-bit I/O ports having equivalent functions to P0.
(however, output of P7_0 and P7_1 for the N-channel open drain
output.)
P8_0 to P8_4,
P8_6, P8_7,
P14_0,
P14_1
(2)
I/O VCC1 I/O ports having equivalent functions to P0.
Input port P8_5 I
VCC1 Input pin for the NMI
interrupt.
Pin states can be read by the P8_5 bit in the P8 register.
