4.2
The PIC24F core has a separate, 16-bit wide data
memory 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 displayed
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 (PSV) area
(see Section 4.3.3 “Reading Data From Program
Memory Using Program Space Visibility”).
PIC24F16KA102 family devices implement a total of
768 words 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 the
data space EAs resolve to bytes. The Least Significant
Bytes (LSBs) of each word have even addresses, while
the Most Significant Bytes (MSBs) have odd
addresses.
