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

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>

determine

user

configuration 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.
