Port 2 Pin Functions (cont)
Selection Method and Pin Functions
This pin is used as the 8-bit timer counter reset pin when bits CCLR1 and
CCLR0 in TCR1 are both set to 1.
The pin function is switched as shown below according to the combination of
the TPU channel 4 setting by bits MD3 to MD0 in TMDR4, bits IOA3 to IOA0 in
TIOR4, bits CCLR1 and CCLR0 in TCR4, and bit P24DDR.
Notes: 1. TIOCA4 input when TPU channel 4 is in normal operation mode
