I am currently connecting an AVR ATXmega 16A4U in my circuit. According to AVR (http://www.atmel.com/Images/doc8278.pdf, p6) the external reset circuit should look like
simulate this circuit – Schematic created using CircuitLab
But I want to use the RESET/PDI_CLK-Pin also for programming. For this case AVR suggests to remove all capacitance from the reset line.
What should I omit now: The capacitor, or should I risk getting a smeared CLK-signal while programming the µC?
