Op Code: 42 1E
leaves the value BDh (10111101b) in Working Register R1. The S Flag is
set, and the Z and V flags are cleared.
Example

R13 contains 7Bh, and Register 7B contains 6Ah (01101010b), the state-
ment:
OR R4, @R13
Op Code: 43 4D
leaves the value FBh (11111011b) 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 (00001010), the statement:
