Data Shift Instructions
Section 3-9
If as a result of the shift the contents of the leftmost bit of Wd + 1 is 1, the Neg-
ative Flag will turn ON.
Note
It is possible to set the Carry Flag contents to 1 or 0 immediately before exe-
cuting this instruction, by using the Set Carry (STC(040)) or Clear Carry
(CLC(041)) instructions.
Examples
When CIO 000000 is ON, word CIO 0100, CIO 0101 and the Carry Flag (CY)
will shift one bit to the right. The contents of CIO 010000 will be shifted to the
Carry Flag (CY) and the Carry Flag contents will be shifted to CIO 010115.
3-9-13 ROTATE LEFT WITHOUT CARRY: RLNC(574)
Purpose
Shifts all Wd bits one bit to the left not including the Carry Flag (CY).
