Section 9 I/O Ports
9.11.3
Port F pins also function as external interrupt input pins (IRQ2 and IRQ3), A/D trigger input pin
(ADTRG), bus control signal input/output pins (AS, RD, HWR, LWR), and the system clock (φ)
output pin. The pin functions differ between modes 4 to 6, and mode 7. Port F pin functions are
shown in table 9-21.
