The IPL Status bits are read-only when NSTDIS (INTCON1<15>) = 1.
The IPL Status bits are concatenated with the IPL3 bit (CORCON<3>) to form the CPU Interrupt Priority
Level (IPL). The value in parentheses indicates the IPL when IPL3 = 1.
Unimplemented: Read as ‘0’
DC: ALU Half Carry/Borrow bit
1 = A carry-out from the 4th low-order bit (for byte-sized data) or 8th low-order bit (for word-sized data)
0 = No carry-out from the 4th or 8th low-order bit of the result has occurred
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)
RA: REPEAT Loop Active bit
1 = REPEAT loop in progress
0 = REPEAT loop not in progress
N: ALU Negative bit
1 = Result was negative
0 = Result was non-negative (zero or positive)
OV: ALU Overflow bit
1 = Overflow occurred for signed (2’s complement) arithmetic in this arithmetic operation
0 = No overflow has occurred
Z: ALU Zero bit
1 = An operation which effects the Z bit has set it at some time in the past
0 = The most recent operation which effects the Z bit has cleared it (i.e., a non-zero result)
C: ALU Carry/Borrow bit
1 = A carry-out from the Most Significant bit of the result occurred
0 = No carry-out from the Most Significant bit of the result occurred
