Pin
P16/PO14/
TIOCA2/IRQ1
Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
the TPU channel 2 setting (by bits MD3 to MD0 in TMDR2, bits IOA3 to IOA0
in TIOR2, and bits CCLR1 and CCLR0 in TCR2), bit NDER14 in NDERH, and
bit P16DDR.
Notes: *1 TIOCA2 input when MD3 to MD0 = B'0000 or B'01xx, and IOA3 =
