3.1.1
The
word-addressable blocks. Although it is treated as
24 bits wide, it is more appropriate to think of each
address of the program memory as a lower and upper
word, with the upper byte of the upper word being
unimplemented. The lower word always has an even
address, while the upper word has an odd address
(Figure 3-2).
Program memory addresses are always word-aligned
on the lower word, and addresses are incremented or
decremented by two during code execution. This
arrangement also provides compatibility with data
memory space addressing and makes it possible to
access data in the program memory space.

All dsPIC33F devices reserve the addresses between
0x00000 and 0x000200 for hard-coded program exe-
cution vectors. A hardware Reset vector is provided to
redirect code execution from the default value of the
PC on device Reset to the actual start of code. A GOTO
instruction is programmed by the user at 0x000000,
with the actual address for the start of code at
0x000002.
dsPIC33F devices also have two interrupt vector
tables, located from 0x000004 to 0x0000FF and
0x000100 to 0x0001FF. These vector tables allow each
of the many device interrupt sources to be handled by
separate Interrupt Service Routines (ISRs). A more
detailed discussion of the interrupt vector tables is
provided in Section 6.1 “Interrupt Vector Table”.
