Despite a capacitor in the reset line is not directly required for the MCU. In some cases, in order to add a further ESD protection,an external capacitor is added between the RESET pin to ground. The values of the pull up resistor and the capacitor must be selected according to the design requirements of the application. Refer to the device datasheet for the minimum RESET pulse value that can be detected for the MCU.

customer add 0.uf CAN in RESET pin to GND, it has download code issue.

customer need nxp to provide the CAP range? the  detail issue check attched file.
