Pin
P2₀/TIOCA3
Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the TPU channel 3 setting by bits MD3 to MD0 in TMDR3, bits IOA3 to IOA0 in
TIOR3H, bits CCLR2 to CCLR0 in TCR3, and bit P20DDR.

Notes: 1. TIOCA3 input when TPU channel 3 is in normal operation mode
(MD3 to MD0 = B'0000) and input capture is set (IOA3 to IOA0 =
B'10xx).
2. TIOCB3 output is disabled.
