Note: * When this pin is used as an external interrupt input pin, this pin must not be used as an I/O
Pin Functions of H8S/2212 Group
The port F is a 3-bit I/O port. Port F pins also function as external interrupt input (IRQ2, IRQ3)
pins and system clock output (φ) pins. The correspondence between the register specification and
the pin functions is shown below.
