output).

CEC I/O

CEC

I/O

VCC1

CEC I/O (N-channel open drain output).

Reference voltage

input

VREF

VCC1

Reference voltage input for the A/D and D/A converters.

A/D converter

AN0 to AN7

VCC1

Analog input.

AN0_0 to AN0_7

AN2_0 to AN2_7

IVCC2

ADTRG

VCC1

External trigger input.

ANEX0, ANEX1

VCC1

Extended analog input.

D/A converter

DA0, DA1

I/O ports

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

I/O

VCC2

8-bit CMOS I/O ports. A direction register determines

whether each pin is used as an input port or an output

port. A pull-up resistor may be enabled or disabled for

input ports in 4-bit units.

P6_0 to P6_7

P7_0 to P7_7

P8_0 to P8_7

P9_0 to P9_7

P10_0 to P10_7

I/O

VCC1

8-bit I/O ports having equivalent functions to P0.

However, P7_0, P7_1, and P8_5 are N-channel open

drain output ports. No pull-up resistor is provided. P8_5

is an input port for verifying the

NMI pin level and shares

a pin with

NMI.
