High Time of PWM
High Time = (Duty Cycle High Byte:Duty Cycle Low
Byte) / 32768
Duty Cycle = High Time / Period High:Period Low
Max High Time = (Duty Cycle High Byte:Duty Cycle Low
Byte) / 32768
Duty Cycle = Max High Time / Period High:Period Low
Minimum Duty Cycle Output (PWM High Time)
Min High Time = (Duty Cycle High Byte:Duty Cycle Low
