LPC11U68 ISP mode always active irrespective of ISP switch status

Question asked by Imran Munshi on Jan 4, 2017

I use an LPC11U68 chip in one of my schematics. It is a bus powered application.

The problem is that whenever the MCU is plugged in it automatically gets enumerated as a Mass Storage Device (CRP DISABLED) each and every time.


I have attached the svg plot of the MCU part of my board.

I no matter what the switch position is, it always enters ISP mode...
