3.1
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.

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, Program Space
Address Construction, bit 23 allows access to the
Device ID, the User ID and the Configuration bits.
Otherwise, bit 23 is always clear.
