CCRB

CCRA

0x3FF

Counter

Value

CCRA = 0

Counter overflows

CCRB Int.

Flag TnBF

CCRA Int.

Flag TnAF

CCRA > 0 Counter cleared by CCRA value

TPnB O/P Pin

TnON bit

Pause

Counter

Reset

Output Pin

Reset to initial value

Output Pin set

to Initial Level

Low if TnBOC = 0

Output Toggle

with TnBF flag

Here TnBIO1, TnBIO0 = 11

Toggle Output Select

Now TnBIO 1, TnBIO 0 = 10

Act ive High Output Select

Output not aff ected by TnBF flag

remains High until reset by TnON bit

TnPAU bit

Resume

Stop

Time

No TnAF flag

generated on

CCRA overflow

CCRA = 0

Out put inverts

when TnBPO L is high

TnBPOL bit

TnCCLR = 1; TnBM1, TnBM0 = 00

ETM CCRB Compare Match Output Mode

- TnCCLR = 1

Note:

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

2. TPnB output pin controlled only by TnBF flag

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

4. TnPF flags not generated when TnCCLR = 1
