See Register 2-1 for the description of the remaining bit(s) that are not dedicated to interrupt control
functions.
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 IPL Status bits are read-only when NSTDIS (INTCON1<15>) = 1.
See Register 2-2 for the description of the remaining bit(s) that are not dedicated to interrupt control
functions.
The IPL3 bit is concatenated with the IPL2:IPL0 bits (SR<7:5>) to form the CPU interrupt priority level.
IPL2:IPL0: CPU Interrupt Priority Level Status bits
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)
IPL3: CPU Interrupt Priority Level Status bit
1 = CPU interrupt priority level is greater than 7
0 = CPU interrupt priority level is 7 or less
