P24/TIOCA1/A12/AD12
When the TIOCA1S bit in PTCNT2 is cleared to 0, this pin can be used as the TIOCA1 pin.
According to operating modes, the TPU channel 1 settings by the MD3 to MD0 bits in
TMDR_1, the IOA3 to IOA0 bits in TIOR_1, and the CCLR1 and CCLR0 bits in TCR_1, and
the combination of the TIOCA1S bit and the P24DDR bit, pin functions change as follows.

Notes: 1. When TIOCA1S = 0, MD3 to MD0 = B'0000 or B'01xx, and IOA3 to IOA0 = B'10xx, this
pin functions as the TIOCA1 input pin.
2. Output is disabled for TIOCB1.
