To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and * enhanced as new volumes and updates are introduced. * If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via * E-mail at docerrors@microchip.com. We welcome your feedback. * Most Current Documentation * To obtain the most up-to-date version of this documentation, please register at our Worldwide Web site at: * http://www.microchip.com * You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page. * The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000). * Errata * An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur- * rent devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the * revision 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) * When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are * using. * Customer Notification System * Register on our web site at www.microchip.com to receive the most current information on all of our products. * * * */ }
