[Description]
• The exclusive logical sum of bit data of the destination operand (dst) specified by the 1st operand and the
source operand (src) specified by the 2nd operand is obtained and the result is stored in the destination
operand (dst).
• The operation result is stored in the CY flag (because of the destination operand (dst)).

XOR1 CY, A.7; The exclusive logical sum of the A register bit 7 and the CY flag is obtained and the result
is stored in the CY flag.
