Define the ON time based on time unit set in PWM-N setup register
‘00’ : 1 time unit
‘01’ : 2 time unit
‘10’ : 3 time unit
‘11’ : 4 time unit
Define the OFF time based on time unit set in PWM-N setup register
‘00’ : 1 time unit
‘01’ : 2 time unit
‘10’ : 3 time unit
‘11’ : 4 time unit
Set the repetition of programmed sequence (pair of period 0 and period 1)
‘000’ : Infinite repetition
‘001’ : Execute only one pair
‘010’ : Execute 2 pairs
‘011’ : Execute 3 pairs
‘100’ : Execute 4 pairs
‘101’ : Execute 5 pairs
‘110’ : Execute 6 pairs
‘111’ : Execute 7 pairs
Set the order of period 0 and period 1
‘1’ : sequence = period 1 and then period 0
‘0’ : sequence = period 0 and then eriod 1
