Section 9 I/O Ports
9.2.3
Port 1 pins also function as PPG output pins (PO15 to PO8), TPU I/O pins (TCLKA, TCLKB,
TCLKC, TCLKD, TIOCA0, TIOCB0, TIOCC0, TIOCD0, TIOCA1, TIOCB1, TIOCA2, and
TIOCB2), and external interrupt input pins (IRQ0 and IRQ1). Port 1 pin functions are shown in
table 9.3.

Pin Functions
Port 1 Pin Functions
Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the TPU channel 2 setting (by bits MD3 to MD0 in TMDR2, bits IOB3 to IOB0
in TIOR2, and bits CCLR1 and CCLR0 in TCR2), bits TPSC2 to TPSC0 in
TCR0 and TCR5, bit NDER15 in NDERH, and bit P17DDR.
Notes: 1. TIOCB2 input when MD3 to MD0 = B'0000 or B'01xx, and IOB3 =
