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)

bit 4

RA: REPEAT

Loop Active bit

= REPEAT loop in progress

= REPEAT loop not in progress

bit 3

MCU ALU Negative bit

= Result was negative

= Result was non-negative (zero or positive)

bit 2

OV:

MCU ALU Overflow bit

This bit is used for signed arithmetic (2’s complement). It indicates an overflow of a magnitude that

causes the sign bit to change state.

= Overflow occurred for signed arithmetic (in this arithmetic operation)

= No overflow occurred

bit 1

MCU ALU Zero bit

= An operation that affects the Z bit has set it at some time in the past

= The most recent operation that affects the Z bit has cleared it (i.e., a non-zero result)

bit 0

MCU ALU Carry/Borrow bit

= A carry-out from the Most Significant bit of the result occurred

= No carry-out from the Most Significant bit of the result occurred

SR: CPU STATUS REGISTER (CONTINUED)

Note 1:

This bit can be read or cleared (not set).

The IPL<2:0> bits are concatenated with the IPL<3> bit (CORCON<3>) to form the CPU Interrupt Priority

Level (IPL). 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>).

Clearing this bit will clear SA and SB.
