SLRS065A – SEPTEMBER 2013 – REVISED NOVEMBER 2013
Case 5: Timer enable bit (C8) is 0, Energizing Timing bits (C4:C1) are NOT 0000, and PWM Duty bits
(C7:C5) are NOT 000
PWM Start Special Command Used
The output is turned on in Energizing mode with 100% duty cycle, and a timer is enabled with duration set by
Control register bits C4:C1. If the PWM Start special command is received before the timer expires, then the
output switches to PWM chopping mode with PWM Duty Cycle defined by Control register bits C7:C5. If the timer
expires and no PWM Start is received, then the device will stay in Energizing mode regardless of other PWM
Start commands.
