Data Shift Instructions
Section 3-9
Description
WSFT(016) shifts data from St to E in word units and the data from the source
word S is places into St. The contents 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 WSFT(016) is being executed,
causing the shift operation to stop halfway through.
Examples
When CIO 000000 is ON, data from CIO 0100 through CIO 0102 will be
shifted one word toward E. The contents of CIO 0300 will be stored in
CIO 0100 and the contents of CIO 0102 will be lost.
