Lpc2000

Hi. What would be the software sequence the most similar to a 
hardware reset? I am aware that certain things cannot be changed from 
software, like the watchdog, once it is started, but perhaps there's 
something closer to a reset than:

msr   CPSR_c,#MODE_SVC|I_BIT|F_BIT
b 0

This would not work if in user mode, for instance, for I cannot 
change CPSR from that mode, I guess.

I am using LPC2138/LPC2148 in my board. Perhaps the IAP/ISP code 
could be useful somehow?

I've been thinking on reusing an existing exception to start 
such "software reset", like Undefined or something, but I rather use 
it to detect the true exception if I can manage. I would like to 
write a solid piece of software, so I want all the bases covered, 
whenever possible.

Any ideas?
