Lpc2000

Yup There shore is !

In the LPC2106 anyway. I dunno about the rest of them. But it requrires a reset of the micro!

Use the IAP instructions to erase the first block of flash memory.

Drop the supply and bring it up again, and the chip detects the lost of a valid program 
and automatically jumps to the ISP.

I use this to update the firmware with P0.14 buried deep in a hunk of expoxy, but watch it,
Once the ISP is running anyone can steal your program !! I use a very unlikely pass code in the operating firmware to do this.

Is there any way to launch the ISP software without having the BSL
jumper on?  (i.e. does it have an entry point that does not check P0.14?)
