CMP 

PWM Comparator Register 

CMP use to compare with CNTR to generate PWM waveform, interrupt and trigger 
EADC/DAC. 

In independent mode, CMPDAT0~5 denote as 6 independent PWM_CH0~5 compared 
point. 

In complementary mode, CMPDAT0, 2, 4 denote as first compared point, and CMPDAT1, 
3, 5 denote as second compared point for the corresponding 3 complementary pairs 
PWM_CH0 and PWM_CH1, PWM_CH2 and PWM_CH3, PWM_CH4 and PWM_CH5.
