Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the operating mode, TPU channel 0 setting (by bits MD3 to MD0 in TMDR0,
bits IOA3 to IOA0 in TIOR0H, and bits CCLR2 to CCLR0 in TCR0), and bit
P10DDR.

Notes: 1. Modes 1 to 3 are not available on the F-ZTAT version.
Modes 2, 3, 6, and 7 are not available on the ROMless version.
2. TIOCA0 input when TPU channel 0 is in normal operation mode
(MD3 to MD0 = B'0000) and input capture is set (IOA3 to IOA0 =
B'10xx).
3. TIOCB0 output is disabled.
