2.3 Pin Functions - Renesas H8S/2633 Series Hardware Manual

10A.2.3 Pin Functions
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), DMAC output pins (DACK0 and DACK1), external interrupt input pins (IRQ0 and
IRQ1), 14-bit PWM output pins (PWM2 and PWM3), and address bus output pins (A23 to A20).
Port 1 pin functions are shown in table 10A-3.

Pin Selection Method and Pin Functions
P17/PO15/ The pin function is switched as shown below according to the combination of
TIOCB2/PWM3/ the TPU channel 2 setting (by bits MD3 to MD0 in TMDR2, bits IOB3 to IOB0
TCLKD in TIOR2, and bits CCLR1 and CCLR0 in TCR2), bits TPSC2 to TPSC0 in
TCR0 and TCR5, OEB bit in DACR3, bit NDER15 in NDERH, and bit P17DDR.
