The operation of this function is to compare thecorresponding bits of Sa and Sb (B0~B15 or B0~B31), and if bits at the same position have different status,then set the corresponding bit within D as 1, otherwise as 0.• After the operation, if all the bits in D are all 0, then set the 0 flag "D = 0" to 1.X035P.XOREN Sa :Sb :RR01D=0• The instruction at left makes a logical XOR operationusing the R0 and R1 registers, and stores the resultin R2.D :R 2Sa R0 1 0 1 1 1 0 1 1 0 1 1 0 1 1 0 1Sb R1 1 1 1 0 1 1 1 0 1 0 1 0 0 1 1 0 X0=D R2 0 1 0 1 0 1 0 1 1 1 0 0 1 0 1 17-12
