■ Can initiate an ADC sample sequence
The control block determines the polarity of the PWM signals and which signals are passed through
to the pins. The output of the PWM generation blocks are managed by the output control block
before being passed to the device pins. The PWM control block has the following options:
■ 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
■ Synchronization of timer/comparator updates across the PWM generator blocks
■ Extended PWM synchronization of timer/comparator updates across the PWM generator blocks
■ Interrupt status summary of the PWM generator blocks
■ Extended PWM fault handling, with multiple fault signals, programmable polarities, and filtering
■ PWM generators can be operated independently or synchronized with other generators
23.1 Block Diagram
Figure 23-1 on page 1671 provides the TM4C1294NCPDT PWM module diagram and Figure
23-2 on page 1671 provides a more detailed diagram of a TM4C1294NCPDT PWM generator. The
TM4C1294NCPDT controller contains four generator blocks that generate eight independent PWM
signals or four paired PWM signals with dead-band delays inserted.
