Hi,

I meet some question about eTimer module in mpc57xx mcu ,In the compare registor and oflag operate chapter show oflag state can only change state after count reach compare value.

I want make eTimer1_ETC5 io output an square wave in countine counter mode,

So i set eTimer1_ETC5 io as eTimer input/output functon,eTimer as counter mode ,every 10ms toggle oflag state,but i capture eTimer1_ETC5 output waveform is noncorrect. waveform period is 20ms is right,but  waveform voltage just 1.2V and it shape is not a square waveform.
