CPU Control Registers
(1)
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 = 1 (INTCON1<15>).
Unimplemented: Read as ‘0’
DC: MCU 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 low-order bit (for byte-sized data) or 8th low-order bit (for word-sized
IPL<2:0>: 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: MCU ALU Negative bit
1 = Result was negative
0 = Result was non-negative (zero or positive)
OV: MCU ALU Overflow bit
This bit is used for signed arithmetic (2’s complement). It indicates an overflow of the magnitude which
causes the sign bit to change state.
1 = Overflow occurred for signed arithmetic (in this arithmetic operation)
0 = No overflow occurred
Z: MCU ALU Zero bit
1 = An operation which affects the Z bit has set it at some time in the past
0 = The most recent operation which affects the Z bit has cleared it (i.e., a non-zero result)
C: MCU ALU Carry/Borrow bit
1 = A carry-out from the Most Significant bit (MSb) of the result occurred
0 = No carry-out from the Most Significant bit of the result occurred
