An interrupt flag, one for each of the CCRA and CCRP, will be generated when a compare match

occurs from either Comparator A or Comparator P. The TnOC bit in the TMnC1 register is used to

select the required polarity of the PWM waveform while the two TnIO1 and TnIO0 bits are used to

enable the PWM output or to force the TM output pin to a fixed high or low level. The TnPOL bit is

used to reverse the polarity of the PWM output waveform.

Counter cleared

by CCRP

Pause Resume

Counter Stop if

TnON bit low

Counter Reset when

TnON returns high

TnDPX = 0; TnM [1:0] = 10

PWM Duty Cycle

set by CCRA

PWM resumes

operation

Output controlled by

other pin-shared function

Output Inverts

when TnPOL = 1

PWM Period

set by CCRP

TM O/P Pin

(TnOC=0)

PWM Mode — TnDPX = 0

Note: 1. Here TnDPX=0 – Counter cleared by CCRP

2. A counter clear sets the PWM Period

3. The internal PWM function continues running even when TnIO [1:0] = 00 or 01

4. The TnCCLR bit has no influence on PWM operation
