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 2-1, SR: CPU STATUS Register.

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.

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 2-2, CORCON: CORE Control Register.

The IPL3 bit is concatenated with the IPL<2:0> bits (SR<7:5>) to form the CPU Interrupt Priority Level.
