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 6 and 7are concatenated, channel 6 registers become the
high order bytes of the double byte 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.
