We are a leading supplier of: 8-bit general purpose microcontrollers (PIC MCUs) dsPIC30F and dsPIC33F 16-bit Digital Signal Controllers (dsPIC DSCs) Speciality and standard nonvolatile memory devices Security devices (KEELOQ Security ICs) Application-specific standard productsPlease request a Microchip Product Selector Guide for a listing of all the interesting products thatwe have to offer. This literature can be obtained from your local sales office or downloaded fromthe Microchip web site ( ). manual ObjectivePICmicro MCU, dsPIC30F and dsPIC33F devices are grouped by the size of their InstructionWord and Data Path. The current device families :12-bit Instruction Word length, 8-bit Data :14-bit Instruction Word length, 8-bit Data :16-bit Instruction Word length, 8-bit Data :16-bit Instruction Word length, 8-bit Data :24-bit Instruction Word length, 16-bit Data PathThis manual is a software developer s reference for the dsPIC30F and dsPIC33F DSC devicefamilies.

8 This manual describes the Instruction Set in detail and also provides general informationto assist the user in developing software for the dsPIC30F and dsPIC33F manual does not include detailed information about the core, peripherals, system integrationor device-specific information. The user should refer to the dsPIC30F Family reference manual (DS70046) for information about the core, peripherals and system integration. For device-spe-cific information, the user should refer to the individual data sheets. The information that can befound in the data sheets includes: Device memory map Device pinout and packaging details Device electrical specifications List of peripherals included on the deviceCode examples are given throughout this manual . These examples are valid for any device inthe dsPIC30F or dsPIC33F Development SupportMicrochip offers a wide range of development tools that allow users to efficiently develop anddebug application code.

9 Microchip s development tools can be broken down into four categories: Code generation Hardware/Software debug Device programmer Product evaluation boardsInformation about the latest tools, product briefs and user guides can be obtained from theMicrochip web site ( ) or from your local Microchip Sales offers other reference tools to speed the development cycle. These include: Application Notes reference Designs Microchip web site Local Sales Offices with Field Application Support Corporate Support Line The Microchip web site also lists the other sites that may be useful references. 2008 Microchip Technology 1-3 Section 1. Style and Symbol ConventionsThroughout this document, certain style and font format conventions are used. Most formatconventions imply a distinction should be made for the emphasized text. The MCU industry hasmany symbols and non-conventional word definitions/abbreviations.

10 Table 1-1 provides adescription of the conventions used in this 1-1:Document Conventions Symbol or TermDescriptionsetTo force a bit/register to a value of logic 1 .clearTo force a bit/register to a value of logic 0 .Reset1) To force a register/bit to its default state. 2) A condition in which the device places itself after a device Reset occurs. Some bits will be forced to 0 (such as interrupt enable bits), while others will be forced to 1 (such as the I/O data direction bits).0xnnnnDesignates the number nnnn in the hexadecimal number system. These conventions are used in the code examples. For example, 0x013F or 0xA800.: (colon)Used to specify a range or the concatenation of registers/bits/pins. One example is ACCAU:ACCAH:ACCAL, which is the concatenation of three registers to form the 40-bit order (left-right) usually specifies a positional relationship (MSb to LSb, higher to lower).
