Our experiences and expectations are, apparently, almost completely 
reversed.  All the microprocessors I'd used, until I ran into Microchips 
back breaking idea of a data sheet,  had a data sheet that was mostly 
electrical with an overview of the on board peripherals, a user manual 
which sometimes covered several variants, and an architecture and 
instruction set manual which usually covered an entire family.  That was 
true for Intel, Motorola, ST, Siemens and the Japanese manufactures I'd had 
a cursory look at.  When I ran into Microchips data sheet I was quite 
dismayed at what I had to wade through to get basic electrical 
information.  Some of them (Motorola comes to mind) actually had additional 
supplements to describe various peripherals rather than repeat the 
description in multiple user manuals.

Well I don't know about 'most' important ;), but it is equal to the data 
sheet and architecture manual.  And I agree there seems to be something 
about the layout of Philips pages that makes if difficult to find 
literature (and take forever to render).  I've had to read some PIPs 
several times to find either the datasheet or user manual.

On a similar note, from what I can see the best architecture and 
instruction set manual is the "ARM Architecture Reference Manual".  It is 
commercial but you do end up with a proper perfect bound manual for a change.

I do miss TI's logic bible.
