Pin
PB0/A8/
TIOCA3
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
IOA3 to IOA0 in TIOR3H, and bits CCLR2 to CCLR0 in TCR3, and bit PB0DDR.
Notes: *1 TIOCA3 input when MD3 to MD0 = B'0000, and IOA3 to IOA0 = B'10xx.
