= 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

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:
See
for the description of these bits, which are not dedicated to interrupt control functions.
2:
The IPL bits are concatenated with the IPL3 bit (CORCON<3>) to form the CPU Interrupt Priority Level.
The value in parentheses indicates the Interrupt Priority Level if IPL3 = 1.
The value in parentheses indicates the Interrupt Priority Level if IPL3 = 1.
3:
The IPL Status bits are read-only when NSTDIS (INTCON1<15>) = 1.
