5.1
The user-assignable Interrupt Priority (IP<2:0>) bits for
each individual interrupt source are located in the Least
Significant 3 bits of each nibble, within the IPCx
register(s). Bit 3 of each nibble is not used and is read
as a ‘0’. These bits define the priority level assigned to
a particular interrupt by the user.
Since more than one interrupt request source may be
assigned to a specific user specified priority level, a
means is provided to assign priority within a given level.
This method is called “Natural Order Priority” and is
final.
Natural order priority is determined by the position of an
interrupt in the vector table, and only affects interrupt
operation when multiple interrupts with the same user-
assigned priority become pending at the same time.
Table 5-1 lists the interrupt numbers and interrupt
sources for the dsPIC DSC devices and their
associated vector numbers.
The ability for the user to assign every interrupt to one
of seven priority levels implies that the user can assign
a very high overall priority level to an interrupt with a
low natural order priority. The INT0 (external interrupt
0) may be assigned to priority level 1, thus giving it a
very low effective priority.

as the highest priority and 53 as the
lowest priority.
