eCAP speed measurement of dc motor

Hello!

I wanna to measure the speed of the dc motor with eCAP which has Hall Effect encoder. Encoder gives 1 pulse per revolution. I am setting 2 capture events in the eCAP module setting and Enabling Reset Counter After Capture Event 1 time-stamp(and Capture event 2 also).

Do you know what kind of output signal eCAP module gives when TS(time stamp) is the output? is it period expressed in seconds?

And is it Period=CEVT2-CEVT1 (like delta time)?
