The contents of the leftmost bit of Wd shifts to the rightmost bit and to the
Carry Flag (CY).
Flags
Precautions When RLNC(574) is executed, the Error Flag will turn OFF.
If as a result of the shift the contents of Wd is zero, the Equals Flag will turn
ON.
If as a result of the shift the contents of the leftmost bit of Wd is 1, the Nega-
tive Flag will turn ON.
Examples When CIO 000000 is ON, word CIO 0100 will shift one bit to the left (exclud-
ing the Carry Flag (CY)). The contents of CIO 010015 will be shifted to
CIO 010000.
