#90757 - Why memory "mapped"?
Responding to: ???'s previous message
I am always puzzled, why the manufacturers try to make things more complicated than they need to be. But maybe just I am too stupid or missing something, please forgive me.

The "bigger" LPC9xx's are UART-programmable (I don't like the ICP/ISP paradigm, it is too confusing for me). This is accomplished sending intelhex-like records. So there already is a de-facto standard for storing value of UCFG1 (and also other configuration data); and it is as intelhex type 02.

So tell me, please, why felt Philips and Keil it so that they created an another, and quite confusingly memory-mapped, "standard" for storing UCFG1??? Why couldn't the very same programming software interpret intelhex record type 02 the very same way they treat record number 00 address FFF0? Even better, I read on the FlashMagic forum, that Keil changed this address, please, why???

These controllers are complicated enough for themselves, why do they make it worse?

(Sorry, I had a really hard day :-| )
