Data Address Space
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 shown in
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
Depending on the particular device, PIC24F16KL402
family devices implement either 512 or 1024 words of
data memory. If an EA points to a location outside of
this area, an all zero word or byte will be returned.
4.2.1
DATA SPACE WIDTH
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 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.
