Section 9 I/O Ports
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.

Selection Method and Pin Functions
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, and bits CCLR1 and CCLR0 in TCR5), bit NDER7 in NDERL, bits
OS3 to OS0 in TCSR1, and bit P27DDR.
