bit 7 bit 0
Legend:
C = Clear only bit R = Readable bit U = Unimplemented bit, read as ‘0’
S = Set only bit W = Writable bit -n = Value at POR
‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-5 IPL<2:0>: CPU Interrupt Priority Level Status bits
(2)
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: For complete register details, see Register 3-1.
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.

bit 3 IPL3: CPU Interrupt Priority Level Status bit 3
(2)
1 = CPU interrupt priority level is greater than 7
0 = CPU interrupt priority level is 7 or less
Note 1: For complete register details, see Register 3-2.
2: The IPL3 bit is concatenated with the IPL<2:0> bits (SR<7:5>) to form the CPU Interrupt Priority Level.
