The S bit is computed according to its definition (See Section A.5)2. The accumulator value is scaled according to the scaling mode bits SOand S1 in the status register (SR).3. If the accumulator extension is in use, the output of the shifter is limited tothe maximum positive or negative saturation constant, and the L bit is set.-4. The bit test is performed on the resulting 24-bit value, and the jump is takenif the bit tested is clear. The original contents of A or B are not changed.Timing: 6+jx oscillator clock cyclesMemory: 2 program words
