# HRPWM Module

The HRPWM (High Resolution Pulse width Modulator) API provides a set of functions for configuring and using the HRPWM module. The functions provided give access to the HRPWM module which extends the time resolution capability of the ePWM module thus achieving a finer resolution than would be attainable just using the main CPU clock.
