8.3.1
Port 2 is an 8-bit I/O port. Port 2 pins also function as TPU I/O pins (TIOCA3, TIOCB3, TIOCC3,
TIOCD3, TIOCA4, TIOCB4, TIOCA5, and TIOCB5), and 8-bit timer I/O pins (TMRI0, TMCI0,
TMO0, TMRI1, TMCI1, and TMO1). Port 2 pin functions are the same in all operating modes.
Port 2 uses Schmitt-triggered input.
Figure 8.2 shows the port 2 pin configuration.
