Pin Selection Method and Pin Functions
P15/PO13/ The pin function is switched as shown below according to the combination of
TIOCB1/TCLKC 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.
