Pin
Selection Method and Pin Functions
P16/PO14/
The pin function is switched as shown below according to the combination of
TIOCA2/PWM2/
the TPU channel 2 setting (by bits MD3 to MD0 in TMDR2, bits IOA3 to IOA0
IRQ1
in TIOR2, and bits CCLR1 and CCLR0 in TCR2), OEA bit in DACR3, bit
NDER14 in NDERH, and bit P16DDR.
