4.1.1
The program memory space is organized in 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 (see Figure 4-2).
Program memory addresses are always word-aligned
on the lower word, and addresses are incremented or
decremented by two during the code execution. This
arrangement provides compatibility with data memory
space addressing and makes data in the program
memory space accessible.

4.1.2
All dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices reserve the addresses between 0x00000
and 0x000200 for hard-coded program execution vectors.
A hardware Reset vector is provided to redirect code exe-
cution from the default value of the PC on device Reset to
the actual start of code. A GOTO instruction is
programmed by the user application at 0x000000, with
the actual address for the start of code at 0x000002.
The dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/
X04 devices also have two interrupt vector tables, located
from 0x000004 to 0x0000FF and 0x000100 to 0x0001FF.
These vector tables allow each of the 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 7.1
“Interrupt Vector Table”.
