Data Shift Instructions Section 3-8
Examples When CIO 0.00 is ON, CIO 1000 and CIO 1001 will be shifted 10 bits to the
right (from the leftmost bit to the rightmost bit). The number of bits to shift is
specified in bits 0 to 7 of word D300 (control data). The contents of bit 15 of
CIO 1001 will be copied into the bits from which data was shifted and the con-
tents of the leftmost bit of data which was shifted out of range will be shifted
into the Carry Flag (CY). All other data is lost.
