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, and BACK) the system clock ( ) output pin and interrupt input pins (IRQ0 to IRQ3). The
pin functions differ between modes 1, 2, 4, 5, and 6 * , and modes 3 and 7 * . Port F pin functions are
shown in table 8.20.
