Pin
Selection Method and Pin Functions
P16/PO14/
The pin function is switched as shown below according to the combination of the
TIOCA2/
TPU channel 2 settings (by bits MD3 to MD0 in TMDR2, bits IOA3 to IOA0 in
EDRAK2
TIOR2, and bits CCLR1 and CCLR0 in TCR2), bit NDER14 in NDERH, bit
EDRAKE in EDMDR2 and bit P16DDR.
