TnPAU
TnPOL
CCRA Int.
Flag TnAF
CCRP Int.
Flag TnPF
No TnAF flag
generated on
CCRA overflow
TM O/P Pin
TnPF not
generated
Output pin set to
initial Level Low
if TnOC=0
Output Toggle with
TnAF flag
Here TnIO [1:0] = 11
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 initial state by a TnON rising edge
4. The TnPF flag is not generated when TnCCLR = 1
5. n=1~3
