Duty cycle sign
Duty cycle is a positive two’s complement number.
Duty cycle is a negative two’s complement number.
Output is forced to the off-state.
PWM duty cycle high and low bytes
These two bytes, {DUTYH[7:0], DUTYL[7:0]}, form a 14-bit signed value
(Bits 5 and 6 of the High byte are always 0). The value is compared to the
current 12-bit PWM count.
