Pin
PB2/A10/
TIOCC3
Selection Method and Pin Functions
The pin function is switched as shown below according to the operating mode, bits
AE3 to AE0 in PFCR, the TPU channel 3 settings by bits MD3 to MD0 in TMDR3, bits
IOC3 to IOC0 in TIOR3L, and bits CCLR2 to CCLR0 in TCR3, and bit PB2DDR.
Notes: *1 TIOCC3 input when MD3 to MD0 = B'0000, and IOC3 to IOC0 = B'10xx.
