8.1
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.
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 8-1 and Table 8-2 list the interrupt numbers, cor-
responding interrupt sources and associated vector
numbers for the dsPIC30F3014 and dsPIC30F4013
devices respectively.
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.
