Counter

Value

CCRA = 0

Counter overflows

CCRP Int.

Flag TnPF

CCRA Int.

Flag TnAF

CCRA > 0 Counter cleared by CCRA value

TM O/P Pin

TnON bit

Pause

Counter

Reset

Output Pin

Reset to initial value

Output Pin set

to Initial Level

Lowif TnOC= 0

Output Toggle

with TnAF flag

Here TnIO 1, TnIO0 = 11

Toggle Output Select

Now TnIO1, TnIO0 = 10

Act ive High Output

Select

Output not aff ected by TnAF flag

remains High until reset by TnON bit

TnPAU bit

Resume

Stop

Time

TnPF not

generated

No TnAF flag

generated on

CCRA overflow

Out put does

not change

CCRA = 0

Output inverts

when TnPO L is high

TnPOL bit

TnCCLR = 1; TnM1, TnM0 = 00

Compare Match Output Mode

- TnCCLR = 1

Note:

Points to note for above diagram:

1. With TnCCLR = 1 the Comparator A match will clear the counter

2. TM output pin controlled only by TnAF flag

3.TM output pin reset to initial state by TnON rising edge

4. TnPF flags not generated when TnCCLR = 1
