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 3 settings by bits MD3 to MD0 in TMDR3, bits
IOB3 to IOB0 in TIOR3H, and bits CCLR2 to CCLR0 in TCR3, and bit PB1DDR.
Note: * TIOCB3 input when MD3 to MD0 = B'0000, and IOB3 to IOB0 = B'10xx.
