Description
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.
