PWM Comparator Register
CMR determines the PWM duty.
(Unit = one PWM clock cycle)
Note: Any write to CMR will take effect in next PWM cycle.

PWM frequency = PWMxy_CLK/(prescale+1)*(clock divider)/(CNR+1); where
xy, could be 01, 23, 45 or 67, depends on selected PWM channel.
Duty ratio = (CMR+1)/(CNR+1).
CMR >= CNR: PWM output is always high.
CMR < CNR: PWM low width = (CNR-CMR) unit; PWM high width = (CMR+1)
unit.
CMR = 0: PWM low width = (CNR) unit; PWM high width = 1 unit
