PIC24F04KA201 FAMILY
4.1.1
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 4-2).
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.
4.1.2
All PIC24F devices reserve the addresses between
00000h and 000200h 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 at 000000h with
the actual address for the start of code at 000002h.
PIC24F devices also have two interrupt vector tables,
located from 000004h to 0000FFh and 000104h to
0001FFh. These vector tables allow each of the many
