Comparison Instructions Section 3-7
The immediate-refreshing variation (!CMP(020)) can be used with words allo-
cated to external inputs specified in S
1
and/or S
2
. When !CMP(020) is exe-
cuted, input refreshing will be performed for the external input word specified
in S
1
and/or S
2
and that refreshed value will be compared. (Immediate
refreshing cannot be performed on inputs allocated to Group-2 High-density
I/O Units or Units mounted to Slave Racks.)
Flags
Note In CS1-H, CJ1-H, CJ1M, and CS1D (for Single-CPU System) CPU Units,
these Flags are left unchanged.
In CS1 and CJ1 CPU Units, these Flags are turned OFF.
Precautions Do not program another instruction between CMP(020) and an input condition
that accesses the result of CMP(020) because the other instruction might
change the status of the Arithmetic Flags.
