Selection Method and Pin Functions
P17/PO15/
The pin function is switched as shown below according to the combination of the
TIOCB2/
TPU channel 2 settings (by bits MD3 to MD0 in TMDR2, bits IOB3 to IOB0 in
TCLKD/
TIOR2, and bits CCLR1 and CCLR0 in TCR2), bits TPSC2 to TPSC0 in TCR0
EDRAK3
and TCR5, bit NDER15 in NDERH, bit EDRAKE in EDMDR3, and bit P17DDR.
Modes 1, 2, 4, 5, 6, 7 (EXPE = 1)
