19.0 INSTRUCTION SET SUMMARY

The PIC24H instruction set is identical to that of the

PIC24F, and is a subset of the dsPIC30F/33F

instruction set.

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

Table 19-1 shows the general symbols used in

describing the instructions.

The PIC24H instruction set summary in Table 19-2 lists

all the instructions, along with the status flags affected

by each instruction.

Most word or byte-oriented W register instructions

(including barrel shift instructions) have three

operands:

• The first source operand which is typically a

• The second source operand which is typically a

• The destination of the result which is typically a

However, word or byte-oriented file register instruc-

tions have two operands:

• The file register specified by the value ‘f’

• The destination, which could either be the file

‘WREG’

Most bit-oriented instructions (including simple

rotate/shift instructions) have two operands:

• The W register (with or without an address

modifier) or file register (specified by the value of

‘Ws’ or ‘f’)

• The bit in the W register or file register

(specified by a literal value or indirectly by the

contents of register ‘Wb’)

The literal instructions that involve data movement may

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

value is to be loaded (specified by ‘Wb’ or ‘f’)

However, literal instructions that involve arithmetic or

logical operations use some of the following operands:

• The first source operand which is a register ‘Wb’

without any address modifier

• The second source operand which is a literal

value

• The destination of the result (only if not the same

as the first source operand) which is typically a

The control instructions may use some of the following

operands:

• A program memory address

• The mode of the table read and table write

instructions
