24.0
The PIC24F instruction set adds many enhancements
to the previous PIC
taining an easy migration from previous PIC MCU
instruction sets.
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
• Control operations

However, word or byte-oriented file register instructions
have two operands:

Most bit-oriented instructions (including simple rotate/

• 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
