All PWM registers are reset to their default values upon any system reset.

The system bus clock is the only clock required by this module.

PWM half-cycle boundaries occur at both the PWM cycle start and when the
counter equals the modulus, so in edge-aligned operation full-cycles and
half-cycles are equal.
Fault protection also applies during software output control when the
OUTCTLx bits are set. Fault clearing still occurs at half PWM cycle
boundaries while the PWM generator is engaged, PWMEN equals one. But
the OUTx bits can control the PWM pins while the PWM generator is off,
PWMEN equals zero. Thus, fault clearing occurs at IPbus cycles while the
PWM generator is off and at the start of PWM cycles when the generator is
engaged.
