    Naresh,

    The modules are described in the F2806x Technical Reference Guide (linked here for convenience):

    The eCAP is best for measuring the time between edges assuming SYSCLK resolution is adequate.  It will be able to measure even when the time between events is large (it is a 32-bit timer). 

    The HRCAP is better when you need more accuracy (~300ps resolution), but within a shorter time window.


    Thank you,
    Brett
