Register 20: PWM0 Dead-Band Control (PWM0DBCTL), offset 0x068
The PWM0DBCTL register controls the dead-band generator, which produces the PWM0 and PWM1
signals based on the PWM0A and PWM0B signals. When disabled, the PWM0A signal passes through
to the PWM0 signal and the PWM0B signal passes through to the PWM1 signal. When enabled and
inverting the resulting waveform, the PWM0B signal is ignored; the PWM0 signal is generated by
delaying the rising edge(s) of the PWM0A signal by the value in the PWM0DBRISE register (see
page 457), and the PWM1 signal is generated by delaying the falling edge(s) of the PWM0A signal by
the value in the PWM0DBFALL register (see page 458).

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.
Dead-Band Generator Enable
When set, the dead-band generator inserts dead bands into the output
signals; when clear, it simply passes the PWM signals through.
