Section 8 I/O Ports
8.4
8.4.1
Port 3 is a 6-bit I/O port. Port 3 pins also function as SCI I/O pins (TxD0, RxD0, SCK0, TxD1,
RxD1, and SCK1) and interrupt input pins (IRQ4, IRQ5). Port 3 pin functions are the same in all
operating modes. The interrupt input pins (IRQ4, IRQ5) are Schmitt-triggered inputs.
Figure 8.3 shows the port 3 pin configuration.
8.4.2
Table 8.6 shows the port 3 register configuration.
