dsPIC33FJXXXMCX06A/X08A/X10A
4.6
The dsPIC33FJXXXMCX06A/X08A/X10A architecture
uses a 24-bit wide program space and a 16-bit wide
data space. The architecture is also a modified Harvard
scheme, meaning that data can also be present in the
program space. To use this data successfully, it must
be accessed in a way that preserves the alignment of
information in both spaces.
Aside
dsPIC33FJXXXMCX06A/X08A/X10A architecture pro-
vides two methods by which program space can be
accessed during operation:
• Using table instructions to access individual bytes
• Remapping a portion of the program space into
Table instructions allow an application to read or write
to small areas of the program memory. This capability
makes the method ideal for accessing data tables that
need to be updated from time to time. It also allows
access to all bytes of the program word. The
remapping method allows an application to access a
large block of data on a read-only basis, which is ideal
for look ups from a large table of static data. It can only
access the least significant word of the program word.

Since the address ranges for the data and program
spaces are 16 and 24 bits, respectively, a method is
needed to create a 23-bit or 24-bit program address
from 16-bit data registers. The solution depends on the
interface method to be used.
For table operations, the 8-bit Table Page register
(TBLPAG) is used to define a 32K word region within
the program space. This is concatenated with a 16-bit
EA to arrive at a full, 24-bit program space address. In
this format, the Most Significant bit of TBLPAG is used
to determine if the operation occurs in the user memory
(TBLPAG<7> = 0) or the configuration memory
(TBLPAG<7> = 1).
For remapping operations, the 8-bit Program Space
Visibility register (PSVPAG) is used to define a
16K word page in the program space. When the Most
Significant bit of the EA is ‘1’, PSVPAG is concatenated
with the lower 15 bits of the EA to form a 23-bit program
space address. Unlike table operations, this limits
remapping operations strictly to the user memory area.
Table 4-38 and Figure 4-9 show how the program EA is
created for table operations and remapping accesses
from the data EA. Here, P<23:0> refers to a program
space word, whereas D<15:0> refers to a data space
word.
