3.0
3.1
The program address space is 4M instruction words. It
is addressable by 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 successive 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, read/write instructions,
bit 23 allows access to the Device ID, the User ID and
the Configuration bits; otherwise, bit 23 is always clear.
