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, and BACK), the system clock ( ) 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 1 to 3 are not available on the F-ZTAT version.
