5.1
The user assignable Interrupt Priority (IP<2:0>) bits for
each individual interrupt source are located in the LS 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 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. For example, the PLVD (Low
Voltage Detect) can be given a priority of 7. The INT0
(external interrupt 0) may be assigned to priority level
1, thus giving it a very low effective priority.

The user selectable priority levels start at
0, as the lowest priority, and level 7, as the
highest priority.
as the highest priority and 53 as the
lowest priority.
