This bit is available on dsPIC33EPXXXMC20X/50X and dsPIC33EPXXXGP50X devices only.
This bit is always read as ‘0’.
The IPL3 bit is concatenated with the IPL<2:0> bits (SR<7:5>) to form the CPU interrupt priority level.
VAR: Variable Exception Processing Latency Control bit
1 = Variable exception processing enabled
0 = Fixed exception processing enabled
Unimplemented: Read as ‘0’
US<1:0>: DSP Multiply Unsigned/Signed Control bits
11 = Reserved
10 = DSP engine multiplies are mixed-sign
01 = DSP engine multiplies are unsigned
00 = DSP engine multiplies are signed
EDT: Early DO Loop Termination Control bit
1 = Terminate executing DO loop at end of current loop iteration
0 = No effect
DL<2:0>: DO Loop Nesting Level Status bits
111 = 7 DO loops active

001 = 1 DO loop active
000 = 0 DO loops active
SATA: ACCA Saturation Enable bit
1 = Accumulator A saturation enabled
0 = Accumulator A saturation disabled
SATB: ACCB Saturation Enable bit
1 = Accumulator B saturation enabled
0 = Accumulator B saturation disabled
SATDW: Data Space Write from DSP Engine Saturation Enable bit
1 = Data space write saturation enabled
0 = Data space write saturation disabled
ACCSAT: Accumulator Saturation Mode Select bit
1 = 9.31 saturation (super saturation)
0 = 1.31 saturation (normal saturation)
IPL3: CPU Interrupt Priority Level Status bit 3
1 = CPU interrupt priority level is greater than 7
0 = CPU interrupt priority level is 7 or less
