4.2
The PIC24F core has a separate, 16-bit wide data mem-
ory space, addressable as a single linear range. The
data space is accessed using two Address Generation
Units (AGUs), one each for read and write operations.
The data space memory map is shown in Figure 4-3.
All Effective Addresses (EAs) in the data memory space
are 16 bits wide and point to bytes within the data space.
This 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 4.3.3 “Reading Data from Program Memory
Using Program Space Visibility”).

PIC24FJ256GB110 family devices implement a total of
16 Kbytes of data memory. Should an EA point to a
location outside of this area, an all zero word or byte will
be returned.

The
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.
