The 8051 instruction set does not include an instruction to XOR two bit values. Write a subroutine XRB that effectively behaves as an instruction to XOR two bits in the form XRB C, P. This means that the two bit values are stored in C and P, respectively, prior to the calling of the subroutine, and the XORed result should be put back in C. Note: Explain the working of all code.
