9.3.3 Pin Functions
Port 2 pins also function as PPG output pins (PO7 to PO0) and 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 shown in table 9-5.

The pin function is switched as shown below according to the combination of
the TPU channel 5 setting by bits MD3 to MD0 in TMDR5, bits IOB3 to IOB0 in
TIOR5, bits CCLR1 and CCLR0 in TCR5, bit NDER7 in NDERL, bits OS3 to
OS0 in TCSR1, and bit P27DDR.
