Section 8 I/O Ports
8.12 Port G
8.12.1 Overview
Port G is a 5-bit I/O port. Port G pins also function as bus control signal output pins (CS0 to CS3,
CS6, CS7). The A/D converter input pin (ADTRG), and interrupt input pins (IRQ6, IRQ7). The
interrupt input pins (IRQ6, IRQ7) are Schmitt-triggered inputs.
Figure 8.24 shows the port G pin configuration.
