ICP Reset Pin Deactivation
« on: October 02, 2008, 12:26:04 pm »
Hello,
I've been using Keil uV and an EMP900 to program my 89LPC935 board.  To get more mobile, I just bought a USB-ICP-LPC9XX programming dongle to use with Flash Magic.  It worked right off the bat except for one minor function.  I cannot find how to set the UCFG1 register.  Simply put, when programming it in ICP mode, I cannot disable the reset pin to make it general IO.  Is there somehow I can do this using Flash Magic and ICP or do I have to modify my board to make ISP work?
Thanks,
Pete

OK, sorry to answer my own post....but I figured it out.  I went into START900.A51 and modified the settings in there and everything works well.

Thanks for posting the solution. Also in Flash Magic you can go to ISP -> Device Configuration to set UCFG1 (and UCFG2 if it exists).
