Pin Selection Method and Pin Functions
P15/TIOCB1/
TCLKC 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, bits CCLR1 and CCLR0 in TCR1, bits TPSC2 to TPSC0 in TCR0,
TCR2, TCR4, and TCR5, and bit P15DDR.
