Pulse Width Modulator (PWM)
Register 5: PWM Output Fault (PWMFAULT), offset 0x010
This register controls the behavior of the PWM outputs in the presence of fault conditions. Both the
fault inputs and debug events are considered fault conditions. On a fault condition, each PWM signal
can be passed through unmodified or driven to a specified value. For outputs that are configured
for pass-through, the debug event handling on the corresponding PWM generator also determines
if the PWM signal continues to be generated.
Fault condition control occurs before the output inverter, so PWM signals driven to a specified value
on fault are inverted if the channel is configured for inversion (therefore, the pin is driven to the
logical complement of the specified value on a fault condition).

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
PWM7 Fault
When set, the PWM7 output signal is driven to a specified value on a
fault condition.
PWM6 Fault
When set, the PWM6 output signal is driven to a specified value on a
fault condition.
PWM5 Fault
When set, the PWM5 output signal is driven to a specified value on a
fault condition.
PWM4 Fault
When set, the PWM4 output signal is driven to a specified value on a
fault condition.
PWM3 Fault
When set, the PWM3 output signal is driven to a specified value on a
fault condition.
PWM2 Fault
When set, the PWM2 output signal is driven to a specified value on a
fault condition.
