Stellaris® LM3S817 Microcontroller
⢠Produces two PWM signals with programmable dead-band delays suitable for driving a
half-H bridge
⢠Can be bypassed, leaving input PWM signals unmodified
â Flexible output control block with PWM output enable of each PWM signal
⢠PWM output enable of each PWM signal
⢠Optional output inversion of each PWM signal (polarity control)
⢠Optional fault handling for each PWM signal
⢠Synchronization of timers in the PWM generator blocks
⢠Interrupt status summary of the PWM generator blocks
â Can initiate an ADC sample sequence
â Power
