CTBL(882) registers a comparison table or registers and comparison table
and starts comparison for the port specified in P and the method specified in
C. Once a comparison table is registered, it is valid until a different table is
registered or until the CPU Unit is switched to PROGRAM mode.
Each time CTBL(882) is executed, comparison is started under the specified
conditions. When using CTBL(882) to start comparison, it is normally suffi-
cient to use the differentiated version (@CTBL(882)) of the instruction or an
execution condition that is turned ON only for one scan.
Note If an interrupt task that has not been registered is specified, a fatal program
error will occur the first time an interrupt is generated.
■ Registering a Comparison Table (C = 0002 or 0003 hex)
If C is set to 0002 or 0003 hex, a comparison table will be registered, but com-
parison will not be started. Comparison is started with INI(880).
■ Registering a Comparison Table and Starting Comparison (C = 0000 or
0001 hex)
If C is set to 0000 or 0001 hex, a comparison table will be registered, and
comparison will be started.
■
Stopping Comparison
Comparison is stopped with INI(880). It makes no difference what instruction
was used to start comparison.
