Hello,

I use lpc2106 and I download a bad programm which is normaly made 
for lcp2124 and this programm acess to registers which doesn't exist 
on lpc2106.
After the download trough the ISP, the lpc2106 doesn't work and I 
can't comunnicate with ISP programm (LPC2000 flash utility, 2.1).

Can a programm destroy the boot loader?
Thank you.
