Pin
PB4/A12/
TIOCA4
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 5 settings by bits MD3 to MD0 in TMDR4, bits
IOA3 to IOA0 in TIOR4, and bits CCLR1 and CCLR0 in TCR4, and bit PB4DDR.
Notes: *1 TIOCA4 input when MD3 to MD0 = B'0000 or B'01xx, and IOA3 to IOA0 =
