8.11 Port F
In the H8S/2218 Group, the port F is an 8-bit I/O port also functioning as external interrupt input
(IRQ2, IRQ3) pins, bus control signal I/O pins, and system clock output pins. In the H8S/2212
Group, the port F is a 3-bit I/O port also functioning as external interrupt input (IRQ2, IRQ3) pins
and system clock output pins. The port F has the following registers.
• Port F data direction register (PFDDR)
• Port F data register (PFDR)
• Port F register (PORTF)
