Output pin set to
initial Level Low
if TnOC=0
Output Toggle with
TnAF flag

Toggle Output select
Output does
not change
Output not affected by
TnAF flag. Remains High
until reset by TnON bit
Output Pin
Output Inverts
when TnPOL is high
Note TnIO [1:0] = 10
Active High Output select
Reset to Initial value
Output controlled by
other pin-shared function
Compare Match Output Mode -- TnCCLR = 1
Note:
1. With TnCCLR=1, a Comparator A match will clear the counter
2. The TM output pin is controlled only by the TnAF flag
3. The output pin is reset to its initial state by a TnON bit rising edge
4. A TnPF flag is not generated when TnCCLR=1
