Flag
OFF: In Target Comparison Mode
for the CTBL instruction, indicates
that comparison is not in progress.
Note:
This flag is always OFF in
range comparison mode for the
CTBL instruction.
ON: In Target Comparison Mode for
the CTBL instruction, indicates that
comparison is in progress.
Note:
Unlike range comparison,
once target value comparison is
started, it is continuously executed.
This bit can be used to confirm
