Section 8 I/O Ports
8.11.3
Port F pins also function as bus control signal input/output pins (AS, RD, HWR, LWR, WAIT,
BREQ, BACK, BREQO, CS4, and CS5) the system clock (φ) output pin and interrupt input pins
(IRQ0 to IRQ3). The pin functions differ between modes 4 to 6 *
functions are shown in table 8.20.
