CPU Control Registers

This bit is available on dsPIC33EPXXXMC20X/50X and dsPIC33EPXXXGP50X devices only.
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 the NSTDIS bit (INTCON1<15>) = 1.
A data write to the SR register can modify the SA and SB bits by either a data write to SA and SB or by
clearing the SAB bit. To avoid a possible SA or SB bit write race condition, the SA and SB bits should not
be modified using bit operations.
OA: Accumulator A Overflow Status bit
1 = Accumulator A has overflowed
0 = Accumulator A has not overflowed
OB: Accumulator B Overflow Status bit
1 = Accumulator B has overflowed
0 = Accumulator B has not overflowed
SA: Accumulator A Saturation ‘Sticky’ Status bit
1 = Accumulator A is saturated or has been saturated at some time
0 = Accumulator A is not saturated
SB: Accumulator B Saturation ‘Sticky’ Status bit
1 = Accumulator B is saturated or has been saturated at some time
0 = Accumulator B is not saturated
OAB: OA || OB Combined Accumulator Overflow Status bit
1 = Accumulators A or B have overflowed
0 = Neither Accumulators A or B have overflowed
SAB: SA || SB Combined Accumulator ‘Sticky’ Status bit
1 = Accumulators A or B are saturated or have been saturated at some time
0 = Neither Accumulator A or B are saturated
DA: DO Loop Active bit
1 = DO loop in progress
0 = DO loop not in progress
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
