13.13 Fault Configure ( FLTCONFIG )
When FLTA or FLTB are in use, if hardware detects any abnormal signals, the status of PMW will shift to inactive
automatically.
13.14 PWM Fault Inputs
The PWM module provides a fault function via FLTA and FLTB tw0 output. To disable the output signals of the PWM is
their main function and as well as to enter an inactive status. When the fault occurs, the hardware will performer
forthwith and shift the PWM in an inactive status; and meanwhile remain power-on connected to the PWM . Under
normal working status, either low or high active can be directed by the users by simple operations.
Each of the fault inputs have two modes of operation
Inactive Mode
If the Fault occurs, the output signals of the PWM is deactivated. The status of the PWM will remain in inactive
and correspond to flag of the FLTxS flag and also set it up. If the PWM need to be recovered in a normal output
working status by the time the Fault flag of the FLTxS status must be cleared by the software.
Cycle-by-Cycle Mode
When the Fault function occurs, the output of the PWM is deactived. The status of the PWM pin will remain in
inactive status and correspond to flag of the FLTxS flag and set it up. When the Fault is relieved, the FLTxS will
be relatively cleared, and the output of the PWM will be recovered to normal working status.
