Flags
Note In CS1 and CJ1 CPU Units, these Flags are turned OFF.
In CS1-H, CJ1-H, CJ1M, and CS1D CPU Units, these Flags are left
unchanged.
Precautions Input comparison instructions cannot be used as right-hand instructions, i.e.,
another instruction must be used between them and the right bus bar.
Examples AND LESS THAN: AND<(310)
When CIO 000000 is ON in the following example, the contents of D00100
and D00200 are compared in as unsigned binary data. If the content of
D00100 is less than that of D00200, CIO 005000 is turned ON and execution
proceeds to the next line. If the content of D00100 is not less than that of
D00200, the remainder of the instruction line is skipped and execution moves
to the next instruction line.
AND SIGNED LESS THAN: AND<S(312)
When CIO 000001 is ON in the following example, the contents of D00110
and D00210 are compared as signed binary data. If the content of D00110 is
less than that of D00210, CIO 005001 is turned ON and execution proceeds
to the next line. If the content of D00110 is not less than that of D00210, the
