Counter Value
CCRP
CCRA
Counter cleared
by CCRP
STDPX = 0; STM [1:0] = 10
Counter Reset when
STON returns high
Pause Resume
Counter Stop if
STON bit low
Time
STON
STPAU
STPOL
CCRA Int.
flag STMAF
CCRP Int.
flag STMPF
STM O/P Pin
(STOC=1)
STM O/P Pin
(STOC=0)
PWM Duty Cycle
set by CCRA
PWM Period
set by CCRP
PWM resumes
operation
Output controlled by
other pin-shared function
Output Inverts
when STPOL = 1
PWM Output Mode – STDPX = 0
Note: 1. Here STDPX=0 – Counter cleared by CCRP
2. A counter clear sets the PWM Period
3. The internal PWM function continues running even when STIO [1:0] = 00 or 01
4. The STCCLR bit has no influence on PWM operation
