Power Surge on a Pin connected After Counter
I am complete with my design, but I have one remaining issue. Please see attached image of the relevant components. Every time I power the board ( PSoC 4 CY8CKIT-049 42xx ) a LED connected to PO_YELLOW pin briefly flashes. I managed to detect it wit an Osciloscop and triggering on it. Pin PO_YELLOW is configured as Strong Drive (High-1) and PI_J2_SINGLE as high impedance digital (Low-0). Just to clarify PO are output pins and PI are input pins, all digital. PI_J2_SINGLE is used as a jumper to hardware connect to another pin on the chip. I can confirm, however, that the culprit is the Counter, which is 16bit UDB. If I connect PO_YELLOW directly on the comp port of the counter the behavior is replicated. Further info for the counter configuration: Period:5 Compare:1 Mode:EqualTo ClockMode:UpCounter
Do you want me share the project?
