Selection Method and Pin Functions
PB4/A12/TIOCA4
The function of this pin changes according to the operating mode and the
setting of bits AE3 to AE0 in PFCR; the TPU4 settings of bits MD3 to MD0 in
TMDR4, bits IOA3 to IOA0 in TIOR4, and the CCLR1 and CCLR0 bits in TCR4;
and the setting of the PB4DDR bit.
