CCRA

CCRA Int.

Flag TnAF

CCRP Int.

Flag TnPF

TPnA Pin

TnAOC = 1

TnON bit

Duty Cycle

set by CCRA

PW M Period set by CCRP

TnAI O1, TnAI O0 = 00

Out put Inactive

Counter Stops

if TnON bit low

Counter reset when

TnON ret urns high

Time

TnAPOL bit

Out put Inverts

When TnAPOL = 1

TPnB Pin

TnBOC = 0

TnPAU bit

Resume

Pause

CCRB

CCRB Int.

Flag TnBF

TPnB Pin

TnBOC = 1

Duty Cycle

set by CCRB

TnAIO1, TnAIO0 = 10 PWM Output

TnAI O1, TnAI O0 = 10

PWM O utput

Counter

Value

TnCCLR = 0;

Mode Bits TnA(B)M1, TnA(B)M0 = 10

TnPWM1/TnPWM0 = 11

PWM Mode

- Centre Aligned

Note:

1. Here TnCCLR = 0 therefore CCRP clears counter and determines PWM period

2. TnPWM1/TnPWM0 = 11 therefore PWM is centre aligned

3. Internal PWM function continues even when TnAIO1, TnAIO0 ( or TnBIO1, TnBIO0) = 00 or 01

4. CCRA controls TPnA PWM duty and CCRB controls TPnB PWM duty
