Pulse Width Modulator (PWM)
Register 3: PWM Output Enable (PWMENABLE), offset 0x008
This register provides a master control of which generated pwmA' and pwmB' signals are output to
the MnPWMn 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 pwmA' or pwmB' signal is passed through to the output stage.
When bits are clear, the pwmA' or pwmB' signal is replaced by a zero value which is also passed
to the output stage. The PWMINVERT register controls the output stage, so if the corresponding
bit is set in that register, the value seen on the MnPWMn signal is inverted from what is configured
by the bits in this register. Updates to the bits in this register can be immediate or locally or globally
synchronized to the next synchronous update as controlled by the ENUPDn fields in the PWMENUPD
register.

Reset Description
0x0000.00 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.
