Hello Piquers!

628 is a charming chip, so I got a stash of them.  Can anyone recommend =
an informational resource(s) for migrating from '84 to '628?  Hoping for =
a practical guide, like an FAQ, or some detailed project examples.  =
Mostly, it would be helpful to read a "plain English" explanation of all =
the new pin functions
, and some logical scenarios for using those functions.

Yes, I already printed out and perused the 62X data sheet.  Sure, it is =
a masterpiece of succinctness, all 158 luscious pages of it, but it is =
hard to penetrate, hard to get straight answers.  That is, it is not =
written in an introductory style.

What makes 62X especially tricky for me is way each pin can do multiple =
new functions, and defaults to those new functions, and must be =
configured to an intended purpose.  I am especially confused by the way =
the MCLR pin is disabled in a certain mode.  How do you program the chip =
when the MCLR does not respond?  I thought MCLR was necessary to =
initiate the programming process.  For ICSP, can MCLR be floated, or =
should it be pulled up/down?  And LVP is also a new twist I don't yet =
understand.  These are the kinds of riddles for which a cheat sheet =
would be graciously appreciated.

Methinks the 16F62X deserves a book: "PIC16F62X for Dummies"

Thank you for any illumination you may provide.

James Salter
