for example if you compare the very old Intel data manuals MCS51 and the PCA cookbook with the Philips data manuals for the 8051/52 you will find the Philips has left out almost all important details.
HUH???
1) Philips never had a PCA cookbook
2) I have the old MCS-51 book and there is nothing missing (except the datasheets for archaic devices, which hardly count as 'important details') in "the bible". having the book, I most often refer to "the bible", the book does not have 'search'
