I don't understand this, what are you telling us that Atmel opens 
their software specs? try to get from them the debug-write specs then!
I don't belive if somebody picked chip X or Y the reason is for the 
open software programming specs.
LPCs have their strong side - easy to learn, less features to confuse 
the beginner, smooth learning curve for peoples who move from 8-bits
this in other hand is their weak side later on - too infantile 
peripherials, no DMA channels etc, SAM7S256(same price range as 
LPC2124) for instance have 11 DMA channels connected to every 
peripherial which relief the CPU from overhead waiting to read this 
or that peripheral, so I bet the Swedish company moved to Atmel due 
to other reasons than the programming specs.
perhaphs the way Philips to go is to keep this high-runner entry 
series, but to introduce one more sophisticated serie which to keep 
to them the peoples who want some more power from the ARMs :)
