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 input and debug events are considered fault conditions. On a fault condition, each PWM signal
can either be passed through unmodified or driven Low. 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 happens before the output inverter, so PWM signals driven Low on fault are
inverted if the channel is configured for inversion (therefore, the pin is driven High 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.
PWM5 Driven Low on Fault
When set, the PWM5 output signal is driven Low on a fault condition.
PWM4 Driven Low on Fault
When set, the PWM4 output signal is driven Low on a fault condition.
PWM3 Driven Low on Fault
When set, the PWM3 output signal is driven Low on a fault condition.
PWM2 Driven Low on Fault
When set, the PWM2 output signal is driven Low on a fault condition.
PWM1 Driven Low on Fault
When set, the PWM1 output signal is driven Low on a fault condition.
PWM0 Driven Low on Fault
When set, the PWM0 output signal is driven Low on a fault condition.
