Section 9 I/O Ports
9.13 Port G
9.13.1 Overview
Port G is a 5-bit I/O port. Port G pins also function as external interrupt input pins (IRQ6 and
IRQ7) and bus control signal output pins (CS0 to CS3).
The interrupt input pins (IRQ6 and IRQ7) are Schmitt-triggered inputs.
Figure 9.19 shows the port G pin configuration.
