The PWMCTL register provides for various control of the PWM module.
Read: anytime
Write: anytime
There are three control bits for concatenation, each of which is used to concatenate a pair of PWM channels
into one 16-bit channel. When channels 4 and 5 are concatenated, channel 4 registers become the
high-order bytes of the double-byte 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.
