Function

Note • The above shift operations are applicable when the reset bit (bit 15 of C) is set to OFF.

• When reset (bit 15 of C) turns ON all bits in the shift register, from St to E will be reset (i.e., set to 0).

Sample program

• Shifting Data

If shift input W0.14 goes ON when CIO 0.00 is ON, and the reset bit W0.15 is OFF, words CIO 100

through CIO 102 will shift one bit in the direction designated by W0.12 (e.g., 1: Right) and the contents

of input bit W0.13 will be shifted into the rightmost bit, CIO 100.00. The contents of CIO 102.15 will be

shifted to the Carry Flag (CY).

• Resetting Data

If W0.14 is ON when CIO 0.00 is ON, and the reset bit, W0.15, is ON, words CIO 100 through CIO 102

and the Carry Flag will be reset to OFF.

 Controlling Data

When the execution condition of

the shift input bit (bit 14 of C)

changes to ON, all the data from

St to E is moved in the designated

shift direction (designated by bit

12 of C) by 1 bit, and the ON/OFF

status of the data input is placed

in the rightmost or leftmost bit.

The bit data shifted out of the shift

Flag (CY)

All bits from St to E and the Carry Flag are set to 0 and

no other data can be received when the reset input bit

(bit 15 of C) is ON.

When the shift input bit (bit 14 of C) is ON, the contents

of the input bit (bit 13 of C) is shifted to bit 00 of the start-

ing word, and each bit thereafter is shifted one bit to the

left. The status of bit 15 of the end word is shifted to the

Carry Flag.

When the shift input bit (bit 14 of C) is ON, the contents

of the input bit (bit 13 of C) (I/O) is shifted to bit 15 on the

end word, and each bit thereafter is shifted one bit to the

right. The status of bit 00 of the starting word is shifted to

the Carry Flag.
