Chapter 11 Pulse Width Modulator with Fault Protection (PMF15B6CV2)
11.4.7.3
With a reload opportunity, regardless an actual reload occurs as determined by LDOK bit, the PWMF
reload flag is set. If the PWM reload interrupt enable bit, PWMRIE is set, the PWMF flag generates CPU
interrupt requests allowing software to calculate new PWM parameters in real time. When PWMRIE is
not set, reloads still occur at the selected reload rate without generating CPU interrupt requests.
