8.1
The user-assignable interrupt priority bits (IP<2:0>) 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
sources
devices and their associated vector numbers.
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
(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.
