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
Program memory addresses are always word-aligned
on the lower word, and addresses are incremented or
decremented by two during code execution. This
arrangement provides compatibility with data memory
space addressing and makes data in the program
memory space accessible.

4.1.2
All
dsPIC33FJ32(GP/MC)101/102/104 devices reserve
the addresses between 0x00000 and 0x000200 for
hard-coded program execution 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 application at 0x000000, with the actual
address for the start of code at 0x000002.
dsPIC33FJ16(GP/MC)101/102 and dsPIC33FJ32(GP/
MC)101/102/104 devices also have two Interrupt Vec-
tor Tables (IVTs), 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
