4.2
The dsPIC33FJXXXMCX06/X08/X10 CPU has a sepa-
rate 16-bit wide data memory space. The data space is
accessed using separate Address Generation Units
(AGUs) for read and write operations. Data memory
maps of devices with different RAM sizes are shown in
Figure 4-3 through Figure 4-5.
All Effective Addresses (EAs) in the data memory space
are 16 bits wide and point to bytes within the data space.
This arrangement gives a data space address range of
64 Kbytes or 32K words. The lower half of the data
memory space (that is, when EA<15> = 0) is used for
implemented memory addresses, while the upper half
(EA<15> = 1) is reserved for the Program Space
Visibility area (see Section 4.6.3 “Reading Data from
Program Memory Using Program Space Visibility”).
dsPIC33FJXXXMCX06/X08/X10 devices implement a
total of up to 30 Kbytes of data memory. Should an EA
point to a location outside of this area, an all-zero word
or byte will be returned.
4.2.1
The data memory space is organized in byte
addressable, 16-bit wide blocks. Data is aligned in data
memory and registers as 16-bit words, but all data
space EAs resolve to bytes. The Least Significant
Bytes of each word have even addresses, while the
Most Significant Bytes have odd addresses.
4.2.2
To maintain backward compatibility with PIC
controllers and improve data space memory usage
efficiency,
instruction set supports both word and byte operations.
As a consequence of byte accessibility, all effective
address calculations are internally scaled to step
through word-aligned memory. For example, the core
recognizes
Addressing mode [Ws++] will result in a value of Ws +
1 for byte operations and Ws + 2 for word operations.
Data byte reads will read the complete word that
contains the byte, using the LSb of any EA to determine
which byte to select. The selected byte is placed onto
the LSb of the data path. That is, data memory and reg-
isters are organized as two parallel byte-wide entities
with shared (word) address decode but separate write
lines. Data byte writes only write to the corresponding
side of the array or register which matches the byte
address.

All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap is generated. If the error occurred on a read, the
instruction underway is completed; if it occurred on a
write, the instruction will be executed but the write does
not occur. In either case, a trap is then executed,
allowing the system and/or user to examine the
machine state prior to execution of the address Fault.
All byte loads into any W register are loaded into the
Least Significant Byte. The Most Significant Byte is not
modified.
A sign-extend instruction (SE) is provided to allow
users to translate 8-bit signed data to 16-bit signed
values. Alternatively, for 16-bit unsigned data, users
can clear the MSb of any W register by executing a
zero-extend (ZE) instruction on the appropriate
address.
4.2.3
The first 2 Kbytes of the Near Data Space, from 0x0000
to 0x07FF, is primarily occupied by Special Function
Registers
dsPIC33FJXXXMCX06/X08/X10 core and peripheral
modules for controlling the operation of the device.
SFRs are distributed among the modules that they
control and are generally grouped together by module.
Much of the SFR space contains unused addresses;
these are read as ‘0’.
4.2.4
The 8-Kbyte area between 0x0000 and 0x1FFF is
referred to as the Near Data Space. Locations in this
space are directly addressable via a 13-bit absolute
address field within all memory direct instructions.
Additionally, the whole data space is addressable using
MOV instructions, which support Memory Direct
Addressing mode with a 16-bit address field, or by
using Indirect Addressing mode using a working
register as an Address Pointer.
