Port 8

8-bit input/output port.

Input/output can be specified bit-wise.

When used as an input port, an on-chip pull-up resistor can be

used by software.

Input/output port/segment signal output function can be specified

in 2-bit unit by the LCD display control register (LCDC).

Port 9

8-bit input/output port.

Input/output can be specified bit-wise.

When used as an input port, an on-chip pull-up resistor can be

used by software.

Input/output port/segment signal output function can be specified

in 2-bit unit by the LCD display control register (LCDC).

Port 10

4-bit input/output port.

Input/output can be specified bit-wise.

When used as an input port, an on-chip pull-up resistor can be

used by software.

LEDs can be driven directly.

Port 11

8-bit input/output port.

Input/output can be specified bit-wise.

When used as an input port, an on-chip pull-up resistor can be

used by software.

Falling edge detection capability.

Caution For pins which also function as port pins, do not perform the following operations during A/D

conversion. If these operations are performed, the total error ratings cannot be kept (except for LCD

segment output alternate-function pin).

(1) Rewriting the output latch while the pin is used as a port pin.

(2) Changing the output level of the pin used as an output pin, even if it is not used as a port pin.
