St: Starting word
IR, SR, AR, DM, HR, LR
E: End word
IR, SR, AR, DM, HR, LR
Limitations
St and E must be in the same data area, and St must be less than or equal to E.
Description
When the execution condition is OFF, SLD(74) is not executed. When the execu-
tion condition is ON, SLD(74) shifts data between St and E (inclusive) by one
digit (four bits) to the left. 0 is written into the rightmost digit of the St, and the
content of the leftmost digit of E is lost.
