Pin Function

IRQ3 input pin*

Notes: 1. ADTRG input pin when TRGS0 = TRGS1 = 1.

2. When this pin is used as an external interrupt input pin, this pin must not be used as an

I/O pin for another function.

8.12 Port G

In the H8S/2218 Group, the port G is a 4-bit I/O port also functioning as external interrupt input

(IRQ7) pins and bus control output (CS0 to CS3) pins. In the H8S/2212 Group, the port G is a 2-

bit I/O port also functioning as external interrupt input (IRQ7) pins and H-UDI (TDI) pins. The

port G has the following registers.

• Port G data direction register (PGDDR)

• Port G data register (PGDR)

• Port G register (PORTG)
