Some weeks/months ago, I posted a message here asking how someone should=20
accurately determine which errata sheets apply to which chips, as the err=
ata=20
sheet revision codes did not directly correspond with the batch codes on =
the=20
physical chips.  Responses were underwhelming, so I spoke with Microchip'=
s=20
tech support and though they ran off and came back with some info, they c=
ould=20
not get me any self-sufficient process by which I could find this out.  I=
t=20
seems like I'd have to call and wait some days for a response.

I'm curious why I'm the only one concerned about this.  Isn't anyone else=
=20
(especially the commercial PIC developers, consultants, etc) concerned ab=
out =20
this, or am I missing something here?  Do you just assume all errata shee=
ts=20
apply?  If so, how do you know if some previous issue has been resolved i=
n a=20
later chip revision?  Or ... ???

I'm also curious why this correlation is such a secret within Microchip.

Cheers,
-Neil.
