IPL<2:0>:
CPU Interrupt Priority Level Status bits(1)
111
= CPU Interrupt Priority Level is 7 (15), user interrupts disabled
110
= CPU Interrupt Priority Level is 6 (14)
101
= CPU Interrupt Priority Level is 5 (13)
100
= CPU Interrupt Priority Level is 4 (12)
011
= CPU Interrupt Priority Level is 3 (11)
010
= CPU Interrupt Priority Level is 2 (10)
001
= CPU Interrupt Priority Level is 1 (9)
000
= CPU Interrupt Priority Level is 0 (8)
Note 1:
2:
The IPL<2:0> bits are concatenated with the IPL<3> bit (CORCON<3>) to form the CPU Interrupt Priority
Level. The value in parentheses indicates the IPL if IPL<3> = 1. User interrupts are disabled when
IPL<3> = 1.
3:
The IPL<2:0> Status bits are read-only when NSTDIS (INTCON1<15>) = 1.
