2.2 Pin Configurations for PWM Outputs

The default pin configurations for PWM outputs are shown in Table 2-11. The required connections are six PWM output signals that send the commutation patterns for FOC motor control. TIMA includes features for motor control, such as complimentary PWM outputs with deadband, fault handling with <40ns response time, and repeat counters for configuring FOC loop rates.

TIMA0 can be configured to provide three complimentary pairs of PWM outputs (such as TIMA0_C1 and TIMA0_C1N) and is the preferred timer for motor control applications. but any TIMA0 or TIMA1 output pair can be used and cross-triggered to provide the six PWM output signals.
