if Working Register R12 (CH) is the destination operand, then ECh will be
used as the destination operand in the Op Code.

Example
If Working Register R1 contains 34h (00111000b) and Working Register
R14 contains 4Dh (10001101b), the statement:
XOR R1, R14
Op Code: B2 1E
leaves the value BDh (10111101b) in Working Register R1. The Z, and V
flags are cleared, and the S Flag is set.
Example
If Working Register R4 contains F9h (11111001b), Working Register
R13 contains 7Bh, and Register 7Bh contains 6Ah (01101010b), the
statement:
XOR R4, @R13
Op Code: B3 4D
leaves the value 93h (10010011b) in Working Register R4. The S Flag is
set, and the Z, and V flags are cleared.
Example
If Register 3Ah contains the value F5h (11110101b) and Register 42h
contains the value 0Ah (00001010b), the statement:
XOR 3Ah, 42h
Op Code: B4 42 3A
leaves the value FFh (11111111b) in Register 3Ah. The S Flag is set, and
the C and V flags are cleared.
