ECAP Module

The Enhanced Capture (eCAP) API provides a set of functions for configuring and using the eCAP module. Functions are provided to utilize both the capture and PWM capability of the eCAP module. The APIs allow for the selection and characterization of the input signal to be captured. A provision is also made to provide DMA trigger sources based on the eCAP events. The necessary APIs are also provided for PWM mode of operation.
