OPWMCB: Center Aligned Output Pulse Width Buffered
The Center Aligned Output PWM Buffered with Dead-Time mode (MODE[0:6]=10111bb) is
another way of generating a PWM. The time base can be selected via BSL, and it should be a
up/down MCB counter. It is also recommended to start the MCB channel after starting the
OPWMCB mode.

Register A1 controls the duty cycle for the PWM signal, it is compared with the time base, and
comparisons result in centred pulses thanks to up/down counter. Match on A1 will set the
internal timer to 0x1.
