Section 10 I/O Ports
• P15/PO13/TIOCB1/TCLKC
The pin function is switched as shown below according to the combination of the TPU channel
1 settings (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.

TIOCB1 input^*1
TCLKC input^*2
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 phase counting mode is set for channels 2 and 4.
