R/W-0(3)
R-0
R/W-0
IPL<2:0>(2)

Z
C
bit 7
bit 0
Legend:
C = Clear only bit
R = Readable bit
U = Unimplemented bit, read as ‘0’
S = Set only bit
W = Writable bit
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
OA: Accumulator A Overflow Status bit
1
= Accumulator A overflowed
0
= Accumulator A has not overflowed
bit 14
OB: Accumulator B Overflow Status bit
1
= Accumulator B overflowed
0
= Accumulator B has not overflowed
bit 13
SA: Accumulator A Saturation ‘Sticky’ Status bit(1)
1
= Accumulator A is saturated or has been saturated at some time
0
= Accumulator A is not saturated
bit 12
SB: Accumulator B Saturation ‘Sticky’ Status bit(1)
1
= Accumulator B is saturated or has been saturated at some time
0
= Accumulator B is not saturated
bit 11
OAB: OA || OB Combined Accumulator Overflow Status bit
1
= Accumulators A or B have overflowed
0
= Neither Accumulators A or B have overflowed
bit 10
SAB: SA || SB Combined Accumulator ‘Sticky’ Status bit
1
= Accumulators A or B are saturated or have been saturated at some time in the past
0
= Neither Accumulator A or B are saturated
Note: This bit can be read or cleared (not set). Clearing this bit will clear SA and SB.
bit 9
DA: DO Loop Active bit
1
= DO loop in progress
0
= DO loop not in progress
Note 1:
This bit can be read or cleared (not set).
2:
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.
3:
The IPL<2:0> Status bits are read only when NSTDIS = 1 (INTCON1<15>).
