Figure 9-46. PWM Disable Mapping Write-Once Register (DISMAP)
This write-once register holds an 8-bit value which determines which
PWM pins will be disabled if an external fault or software disable occur.
For a further description of the disable mapping, see
Protection. After this register is written for the first time, it cannot be
rewritten unless a RESET occurs.
This register controls the fault protection circuitry.
