Function
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.
Precautions
• St and E must be in the same data area.
• 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.
