Interrupt Priority
The user-assignable interrupt priority (IP<2:0>) bits for
each individual interrupt source are located in the
3 LSbs 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-assigned 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 8-1 and Table 8-2 list the interrupt numbers,
corresponding 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 means that the user can assign
a very high overall priority level to an interrupt with a
low natural order priority. For example, the PLVD (Pro-
grammable 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.
TABLE 8-1:
dsPIC30F3014 INTERRUPT
VECTOR TABLE
Note:
The user-assignable priority levels start at
0 as the lowest priority and Level 7 as the
highest priority.
Note 1: The natural order priority scheme has 0
as the highest priority and 53 as the
lowest priority.
2: The natural order priority number is the
same as the INT number.
