operating mode and bit PG1DDR.

Operating

Mode

Modes 1, 2, 3, 7*

Modes 4 to 6*

PG1DDR

0101

Pin function

1 input pin

1 output pin

1 input pin

CS3 output pin

IRQ7 interrupt input pin*1

Notes: 1. When this pin is used as an external interrupt input, it should not be

used as an input/output pin with other functions.

2. Modes 2, 3, 6, and 7 cannot be used in the H8S/2240.
