Section 10 I/O Ports
10.2.5
Port 2 pins also function as the pins for PPG outputs, TPU I/Os, interrupt inputs (H8S/2456,
H8S/2456R), 8-bit timer I/Os (H8S/2454), I
correspondence between the register specification and the pin functions is shown below.

The pin function is switched as shown below according to the combination of the TPU channel
5 settings (by bits MD3 to MD0 in TMDR_5, bits IOB3 to IOB0 in TIOR_5, and bits CCLR1
and CCLR0 in TCR_5), bit NDER7 in NDERL of PPG, bit ICE in ICCRA_2 of I
P27DDR, and bit ITS15 in ITSR of the interrupt controller.
