[Description]
The bit-wise logical sum is obtained from the destination operand (dst) specified by the 1st operand and the
source operand (src) specified by the 2nd operand and the result is stored in the destination operand (dst).
If the logical sum shows that all bits are 0, the Z flag is set (1). In all other cases, the Z flag is cleared (0).
[Description example]
OR A, FE98H;
The bit-wise logical sum of the A register and FE98H is obtained and the result is stored in
the A register.
