SESTAT: Special Event Interrupt Status bit
1 = Secondary special event interrupt is pending
0 = Secondary special event interrupt is not pending
SEIEN: Special Event Interrupt Enable bit
1 = Secondary special event interrupt is enabled
0 = Secondary special event interrupt is disabled
EIPU: Enable Immediate Period Updates bit⁽¹⁾
1 = Active Secondary Period register is updated immediately
0 = Active Secondary Period register updates occur on PWM cycle boundaries
SYNCPOL: Synchronize Input and Output Polarity bit
1 = The falling edge of SYNCIN resets the SMTMR; SYNCO2 output is active-low
0 = The rising edge of SYNCIN resets the SMTMR; SYNCO2 output is active-high
SYNCOEN: Secondary Master Time Base Synchronization Enable bit
1 = SYNCO2 output is enabled
0 = SYNCO2 output is disabled
SYNCEN: External Secondary Master Time Base Synchronization Enable bit
1 = External synchronization of secondary time base is enabled
0 = External synchronization of secondary time base is disabled
