Pin
P1₄/TIOCA1
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, bits CCLR1 and CCLR0 in TCR1, and bit P14DDR.

Notes: 1. TIOCA1 input when TPU channel 1 is in normal operation mode
(MD3 to MD0 = B'0000) and input capture is set (IOA3 to IOA0 =
B'10xx).
2. TIOCB1 output is disabled.
