Selection Method and Pin Functions
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 IOA3 to IOA0
in TIOR1, and bits CCLR1 and CCLR0 in TCR1), bit NDER12 in NDERH, and
bit P14DDR.

Notes: 1. TIOCA1 input when MD3 to MD0 = B'0000 or B'01xx, and IOA3 to
IOA0 = B'10xx.
2. TIOCB1 output is disabled.
