Data Shift Instructions
Section 3-9
Description
SLD(074) shifts data between St and E by one digit (4 bits) to the left. “0” is
placed in the rightmost digit (bits 3 to 0 of St), and the content of the leftmost
digit (bits 15 to 12 of E) is lost.
Flags
Precautions
When St is greater than E, an error will be generated and the Error Flag will
turn ON.
Note When large amounts of data are shifted, the instruction execution time is quite
long. Be sure that the power is not cut while SLD(074) is being executed,
causing the shift operation to stop halfway through.
Examples
When CIO 000000 is ON, words CIO 0100 through CIO 0102 will shift by one
digit (4 bits) to the left. A zero will be placed in bits 0 to 3 of word CIO 0100
and the contents of bits 12 to 15 of CIO 0102 will be lost.
