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), and DMAC output pins (DACK0
and DACK1). Port 1 pin functions are shown in table 9-3.

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, 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, B'01××, and IOB3 = 1.
2. TCLKD input when the setting for either TCR0 or TCR5 is: TPSC2
to TPSC0 = B'111.
TCLKD input when channels 2 and 4 are set to phase counting
mode.
