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.

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 instruc-

tions, bit 23 allows access to the Device ID, the User ID

and the Configuration bits. Otherwise, bit 23 is always

clear.

Note: This data sheet summarizes features of this

group of dsPIC30F devices and is not intended to be

a complete reference source. For more information

on the CPU, peripherals, register descriptions and

general device functionality, refer to the “dsPIC30F

Family Reference Manual” (DS70046). For more

information on the device instruction set and pro-

gramming, refer to the “dsPIC30F/33F

Programmer’s Reference Manual” (DS70157).

Note:

The address map shown in Figure 3-1 is

conceptual, and the actual memory con-

figuration may vary across individual

devices depending on available memory.
