There is a separate datasheet and user guide on each "subset" of LPC9xx-s - that's not such a bad thing, but most of the information is the same in both, so you unnecessarily read almost twice as much.

I am referring on info that is really missing. I have already asked here, for example, if I recall, it was about the callibration curve of the internal RC oscillator. The consumption curve is an another missing thing, I found already something missing also around SPI but I don't recall which was that.

"Thanks" to these confusions I still did not get through basic experimenting with these and am still afraid to use them in real workld application - what happens if I do and something else comes up? I am afraid, these chips are still too fresh.

I am not sure but I think the "bible" is still needed most of the time, too.
