8.12.1
Port G is a 5-bit I/O port. Port G pins also function as bus control signal output pins (CS0 to CS3).
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.
