4.3.3
Move instructions provide a greater degree of address-
ing flexibility than other instructions. In addition to the
addressing
instructions, move instructions also support Register
Indirect with Register Offset Addressing mode, also
referred to as Register Indexed mode.
In summary, the following addressing modes are
supported by move instructions:
• Register Direct
• Register Indirect
• Register Indirect Post-modified
• Register Indirect Pre-modified
• Register Indirect with Register Offset (Indexed)
• Register Indirect with Literal Offset
• 8-bit Literal
• 16-bit Literal

Addressing Mode
MOVE INSTRUCTIONS
For the MOV instructions, the addressing
mode specified in the instruction can differ
for the source and destination EA.
However, the 4-bit Wb (Register Offset)
field is shared by both source and
destination (but typically only used by
one).
Not all instructions support all the
addressing modes given above. Individual
instructions may support different subsets
of these addressing modes.

Preliminary
4.3.4
In addition to the addressing modes outlined previously,
some instructions use literal constants of various sizes.
For example, BRA (branch) instructions use 16-bit signed
literals to specify the branch destination directly, whereas
the DISI instruction uses a 14-bit unsigned literal field. In
some instructions, such as ADD Acc, the source of an
operand or result is implied by the opcode itself. Certain
operations, such as NOP, do not have any operands.
4.4
The PIC24FJ16MC101/102 architecture uses a 24-bit-
wide program space and a 16-bit-wide data space. The
architecture is also a modified Harvard scheme, mean-
ing that data can also be present in the program space.
To use this data successfully, it must be accessed in a
way that preserves the alignment of information in both
spaces.
Aside from normal execution, the PIC24FJ16MC101/
102 architecture provides two methods by which
program space can be accessed during operation:
• Using table instructions to access individual
• Remapping a portion of the program space into
Table instructions allow an application to read or write
to small areas of the program memory. This capability
makes the method ideal for accessing data tables that
need to be updated periodically. It also allows access
to all bytes of the program word. The remapping
method allows an application to access a large block of
data on a read-only basis, which is ideal for lookups
from a large table of static data. The application can
only access the lsw of the program word.
