Register 4: PWM Output Inversion (PWMINVERT), offset 0x00C
This register provides a master control of the polarity of the PWM signals on the device pins. The
PWM signals generated by the PWM generator are active High; they can optionally be made active
Low via this register. Disabled PWM channels are also passed through the output inverter (if so
configured) so that inactive channels maintain the correct polarity.

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.
Invert PWM3 Signal
When set, the generated PWM3 signal is inverted.
Invert PWM2 Signal
When set, the generated PWM2 signal is inverted.
Invert PWM1 Signal
When set, the generated PWM1 signal is inverted.
Invert PWM0 Signal
When set, the generated PWM0 signal is inverted.
