tion, the status to be put into the register, the shift pulse, and the reset input.
The control word is allocated as follows:
15 14 13 12
The data in the shift register will be shifted one bit in the direction indicated
by bit 12, shifting one bit out to CY and the status of bit 13 into the other end
whenever SFTR(84) is executed with an ON execution condition as long as
the reset bit is OFF and as long as bit 14 is ON. If SFTR(84) is executed with
an OFF execution condition or if SFTR(84) is executed with bit 14 OFF, the
shift register will remain unchanged. If SFTR(84) is executed with an ON
execution condition and the reset bit (bit 15) is OFF, the entire shift register
and CY will be set to zero.
Indirectly addressed DM word is non-existent. (Content of *DM word

is not BCD, or the DM area boundary has been exceeded.)
St and E are not in the same data area or ST is greater than E.
CY: Receives the status of bit 00 of St or bit 15 of E, depending on the
shift direction.
