28.0
The dsPIC33EP instruction set is almost identical to
that of the dsPIC30F and dsPIC33F. The PIC24EP
instruction set is almost identical to that of the PIC24F
and PIC24H.
Most instructions are a single program memory word
(24 bits). Only three instructions require two program
memory locations.
Each single-word instruction is a 24-bit word, divided
into an 8-bit opcode, which specifies the instruction
type and one or more operands, which further specify
the operation of the instruction.
The instruction set is highly orthogonal and is grouped
into five basic categories:
• Word or byte-oriented operations
• Bit-oriented operations
• Literal operations
• DSP operations
• Control operations

Most bit-oriented instructions (including simple rotate/
shift instructions) have two operands:
• The W register (with or without an address
• The bit in the W register or file register (specified
The literal instructions that involve data movement can
use some of the following operands:
• A literal value to be loaded into a W register or file
• The W register or file register where the literal
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
• The first source operand, which is a register ‘Wb’
• The second source operand, which is a literal
• The destination of the result (only if not the same
The MAC class of DSP instructions can use some of the
following operands:
• The accumulator (A or B) to be used (required
• The W registers to be used as the two operands
• The X and Y address space prefetch operations
• The X and Y address space prefetch destinations
• The accumulator write back destination
The other DSP instructions do not involve any
multiplication and can include:
• The accumulator to be used (required)
• The source or destination operand (designated as
• The amount of shift specified by a W register ‘Wn’
The control instructions can use some of the following
operands:
• A program memory address
• The mode of the table read and table write
