PWM Control Registers
(1)
These bits should be changed only when PTEN = 0. In addition, when using the SYNCI1 feature, the user
application must program the period register with a value that is slightly larger than the expected period of
the external synchronization input signal.
See
Section 24.0 “Peripheral Trigger Generator (PTG) Module”
PTEN: PWM Module Enable bit
1 = PWM module is enabled
0 = PWM module is disabled
Unimplemented: Read as ‘0’
PTSIDL: PWM Time Base Stop in Idle Mode bit
1 = PWM time base halts in CPU Idle mode
0 = PWM time base runs in CPU Idle mode
SESTAT: Special Event Interrupt Status bit
1 = Special Event Interrupt is pending
0 = Special Event Interrupt is not pending
SEIEN: Special Event Interrupt Enable bit
1 = Special Event Interrupt is enabled
0 = Special Event Interrupt is disabled
EIPU: Enable Immediate Period Updates bit
1 = Active Period register is updated immediately
0 = Active Period register updates occur on PWM cycle boundaries
SYNCPOL: Synchronize Input and Output Polarity bit
1 = SYNCI1/SYNCO1 polarity is inverted (active-low)
0 = SYNCI1/SYNCO1 is active-high
SYNCOEN: Primary Time Base Sync Enable bit
1 = SYNCO1 output is enabled
0 = SYNCO1 output is disabled
SYNCEN: External Time Base Synchronization Enable bit
1 = External synchronization of primary time base is enabled
0 = External synchronization of primary time base is disabled
