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 (high side/low side) duty cycle high and low byte (PWMxDH and
PWMxDL) registers (see
PWM signal. This 14-bit signed value is compared to the PWM count value to determine
the PWM output. Reads from these registers always return the values from the temporary
holding registers. The PWM generator does not use the PWM duty cycle value 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.
