MEMORY ORGANIZATION

3.1

Program Address Space

The program address space is 4M instruction words. It

is addressable by a 24-bit value from either the 23-bit

PC, table instruction Effective Address (EA) or data

space EA, when program space is mapped into data

space as defined by Table 3-1. Note that the program

space address is incremented by two between succes-

sive program words in order to provide compatibility

with data space addressing.

FIGURE 3-1:

SPACE MEMORY MAP

User program space access is restricted to the lower

4M instruction word address range (0x000000 to

0x7FFFFE) for all accesses other than TBLRD/TBLWT,

which use TBLPAG<7> to determine user or configura-

tion space access. In Table 3-1, bit 23 allows access to

the Device ID, the User ID and the Configuration bits;

otherwise, bit 23 is always clear.
