Is the Reset_b signal on i.MX25 level-sensitive or edge-sensitive?
I am currently working on a prototype board with i.MX258, and found that the processor keeps running when Reset_b input is asserted low. Untile Reset_b returns high, the processor restarts.
It seems it's a positive edge-triggered singal, only the rising edge leads to a reset event. But it's not clearly stated in the manual, so I want to make sure is it the expected behaviour?
What's the reset timing like?
