Selection Method and Pin Functions
The pin function is switched as shown below according to the operating mode, bits
AE3 to AE0 in PFCR, the TPU channel 5 settings by bits MD3 to MD0 in TMDR5, bits
IOB3 to IOB0 in TIOR5, and bits CCLR1 and CCLR0 in TCR5, and bit PB7DDR.
Note: * TIOCB5 input when MD3 to MD0 = B'0000 or B'01xx, and IOB3 = 1.
