PWMRH and PWMRL—PWM Reload Register High and Low
These two bytes form the 12-bit Reload value, {PWMRH[3:0], PWMRL[7:0]}. This value
sets the PWM period.
The PWM 0–2 H/L Duty Cycle High and Low Byte (PWMxDH and PWMxDL) registers,
(Table 46
compared to the PWM count value to determine the PWM output. Reads from these regis-
ters always return the values from the temporary holding registers. The PWM duty cycle
value is not used by the PWM generator until the next PWM reload event occurs.
Writing a negative value (DUTYH[7] = 1) forces the PWM to be OFF for the full PWM
period. Writing a positive value greater than the 12-bit PWM reload value forces the PWM
to be ON for the full PWM period.
