OUTCR specifies the clock frequency output from the PF7 pin.
8.11.5
Pin Functions of H8S/2218 Group
The port F is an 8-bit I/O port. Port F pins also function as external interrupt input (IRQ2, IRQ3)
pins, bus control signal I/O pins, and system clock output (φ) pins. The correspondence between
the register specification and the pin functions is shown below.
