Errata

An errata sheet may exist for current devices, describing minor operational differences (from the data sheet) and recommended

workarounds. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revi-

sion of silicon and revision of document to which it applies.

To determine if an errata sheet exists for a particular device, please check with one of the following:

• Microchip’s Worldwide Web site; http://www.microchip.com

• Your local Microchip sales office (see last page)

• The Microchip Corporate Literature Center; U.S. FAX: (480) 786-7277

When contacting a sales office or the literature center, please specify which device, revision of silicon and data sheet (include liter-

ature number) you are using.
