DTC<1:0>
Master PWM Duty Cycle Value bits
FLTSTAT: Fault Interrupt Status
1 = Fault Interrupt is pending
0 = No Fault Interrupt is pending
This bit is cleared by setting FLTIEN = 0.
CLSTAT: Current-Limit Interrupt Status bit
1 = Current-limit interrupt is pending
0 = No current-limit interrupt is pending
This bit is cleared by setting CLIEN = 0.
TRGSTAT: Trigger Interrupt Status bit
1 = Trigger interrupt is pending
0 = No trigger interrupt is pending
This bit is cleared by setting TRGIEN = 0.
FLTIEN: Fault Interrupt Enable bit
1 = Fault interrupt enabled
0 = Fault interrupt disabled and FLTSTAT bit is cleared
