Register 3: PWM Output Enable (PWMENABLE), offset 0x008
This register provides a master control of which generated PWM signals are output to device pins.
By disabling a PWM output, the generation process can continue (for example, when the time bases
are synchronized) without driving PWM signals to the pins. When bits in this register are set, the
corresponding PWM signal is passed through to the output stage, which is controlled by the
PWMINVERT register. When bits are not set, the PWM signal is replaced by a zero value which is
also passed to the output stage.

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 Output Enable
When set, allows the generated PWM7 signal to be passed to the device
pin.
PWM6 Output Enable
When set, allows the generated PWM6 signal to be passed to the device
pin.
PWM5 Output Enable
When set, allows the generated PWM5 signal to be passed to the device
pin.
PWM4 Output Enable
When set, allows the generated PWM4 signal to be passed to the device
pin.
PWM3 Output Enable
When set, allows the generated PWM3 signal to be passed to the device
pin.
PWM2 Output Enable
When set, allows the generated PWM2 signal to be passed to the device
pin.
PWM1 Output Enable
When set, allows the generated PWM1 signal to be passed to the device
pin.
