We're working on frequency acquisition with eTimer peripheral of MPC5675K. We got some issue to properly configure it. The RM isn't well documented about input capture mode and how the capture FIFO works. (how to manually empty the FIFO for example), No application notes, No examples.
Anyone had an idea how to "proper" configure the eTimer peripheral for frequency/duty cyle acquisition ? had details about the role of CFWM (Capture FIFO Water Mark) and it's impact on FIFO management ?
