St and E must be in the same data area, and E must be greater than or equal to
St.
DM 6144 to DM 6655 cannot be used for St or E.
When the execution condition is OFF, WSFT(16) is not executed. When the
execution condition is ON, WSFT(16) shifts data between St and E in word units.
Zeros are written into St and the content of E is lost.
