Description

Reference

voltage input

VREF

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

VCC1

Analog input pins for the A/D converter.

ADTRG

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

VCC1

This is the extended analog input pin for the A/D converter.

D/A converter

DA0, DA1

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

P12_7 (2),

P13_0 to

P13_7 (2)

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

VCC1

Input pin for the NMI interrupt.

Pin states can be read by the P8_5 bit in the P8 register.
