4.4
The PIC24HJ12GP201/202 architecture uses a 24-bit-
wide program space and a 16-bit-wide data space. The
architecture is also a modified Harvard scheme, mean-
ing 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 from normal execution, the PIC24HJ12GP201/
202 architecture provides 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 periodically. 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. The application can
only access the lsw 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 MSb 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 MSb
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 4-23 and Figure 4-5 show how the program EA is
created for table operations and remapping accesses
from the data EA.
