LM3S6110 Datasheet, PDF (500/610 Pages) Texas Instruments – Stellaris® LM3S6110 Microcontroller

Pulse Width Modulator (PWM)
14.1
■ 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
Block Diagram
Figure 14-1 on page 500 provides the Stellaris PWM module unit diagram and Figure 14-2 on page 501
provides a more detailed diagram of a Stellaris PWM generator. The LM3S6110 controller contains
one generator block (PWM0) and generates two independent PWM signals or one paired PWM
signal with dead-band delays inserted.
