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 regis-
ter(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.
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 device 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.
