4.0
The dsPIC DSC core contains two independent
Address Generator Units (AGU): the X AGU and Y
AGU. The Y AGU supports word-sized data reads for
the DSP MAC class of instructions only. The dsPIC DSC
AGUs support three types of data addressing:
• Linear Addressing
• Modulo (Circular) Addressing
• Bit-Reversed Addressing
Linear and Modulo Data Addressing modes can be
applied to data space or program space. Bit-Reversed
Addressing is only applicable to data space addresses.
4.1
The addressing modes in Table 4-1 form the basis of
the addressing modes optimized to support the specific
features of individual instructions. The addressing
modes provided in the MAC class of instructions are
somewhat different from those in the other instruction
types.

FUNDAMENTAL ADDRESSING MODES SUPPORTED
The address of the file register is specified explicitly.
The contents of a register are accessed directly.
The contents of Wn forms the EA.
The contents of Wn forms the EA. Wn is post-modified (incremented or
decremented) by a constant value.
Wn is pre-modified (incremented or decremented) by a signed constant value
to form the EA.
The sum of Wn and a literal forms the EA.
4.1.1
Most file register instructions use a 13-bit address field
(f) to directly address data present in the first 8192 bytes
of data memory (near data space). Most file register
instructions employ a working register W0, which is
denoted as WREG in these instructions. The destination
is typically either the same file register, or WREG (with
the exception of the MUL instruction), which writes the
result to a register or register pair. The MOV instruction
allows additional flexibility and can access the entire
data space during file register operation.
4.1.2
The three-operand MCU instructions are of the form:
where Operand 1 is always a working register (i.e., the
addressing mode can only be Register Direct), which is
referred to as Wb. Operand 2 can be a W register,
fetched from data memory, or a 5-bit literal. The result
location can be either a W register or an address
location.
supported by MCU instructions:
• Register Direct
• Register Indirect
• Register Indirect Post-Modified
• Register Indirect Pre-Modified
• 5-bit or 10-bit Literal
