bit 7-5
IPL<2:0>: CPU Interrupt Priority Level Status bits(2,3)
111 = CPU Interrupt Priority Level is 7 (15); user interrupts are 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)

See Register 3-1 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.
