8.11.1
Port F is an 8-bit I/O port. 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 interrupt input pins (IRQ0 to IRQ3) are Schmitt-triggered inputs.
Figure 8.23 shows the port F pin configuration.
Note: * Modes 6 and 7 are not available in the ROMless versions.
