Shift Instructions Section 5-16
Example The following example uses the 1-second clock pulse bit (25502) so that the
execution condition produced by 00000 is shifted into IR 010 every second.
Output 10000 is turned ON whenever a “1” is shifted into 01007.
5-16-2 WORD SHIFT – WSFT(16)
Limitations 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.
Description 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.
Flags ER: The St and E words are in different areas, or St is greater than E.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
5-16-3 ARITHMETIC SHIFT LEFT – ASL(25)
Limitations DM 6144 to DM 6655 cannot be used for Wd.
