12.2 Architecture Overview

The PWM module consists of a common set of controls and features, and multiple instantiations of PWM Generators (PGs). Each PWM Generator can be independently configured or multiple PWM Generators can be used to achieve complex multiphase systems. PWM Generators can also be used to implement sophisticated triggering, protection and logic functions. A high-level block diagram is shown in Figure 12-1. In addition, this device family has another identical PWM module to accommodate additional PWM Generators. This additional module has been designated as an Auxiliary PWM Module (Figure 12-2). For devices with more than 8 PWM Generators, 8 PWM Generators are regular PWM Generators and any additional generators are APWM Generators.
