12.3.2.6
The PWMCTL register provides for various control of the PWM module.
Read: anytime
Write: anytime
There are control bits for concatenation, each of which is used to concatenate a pair of PWM channels into
one 16-bit channel. When channels 2 and 3 are concatenated, channel 2 registers become the high-order
bytes of the double-byte channel. When channels 0 and 1 are concatenated, channel 0 registers become the
high-order bytes of the double-byte channel.
