This document contains device-specific information. Additional information may be found in the PIC Mid Range Reference Manual (DS33023), which may be obtained from your local Microchip Sales Representative or downloaded from the Microchip website. The Reference manual should be considered a complementary document to this data sheet. The Reference manual is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules.
