P15/PO13/
TIOCB1/TCLKC
Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the TPU channel 1 setting (by bits MD3 to MD0 in TMDR1, bits IOB3 to IOB0
in TIOR1, and bits CCLR1 and CCLR0 in TCR1), bits TPSC2 to TPSC0 in
TCR0, TCR2, TCR4, and TCR5, bit NDER13 in NDERH, and bit P15DDR.

Pin function
Notes: 1. TIOCB1 input when MD3 to MD0 = B'0000 or B'01xx, and IOB3
to IOB0 = B'10xx.
2. TCLKC input when the setting for either TCR0 or TCR2 is: TPSC2
to TPSC0 = B'110; or when the setting for either TCR4 or TCR5 is
TPSC2 to TPSC0 = B'101.
TCLKC input when channels 2 and 4 are set to phase counting
mode.
