Saving and Loading Condition Flag Status
The CP1-H CPU Units support instructions to save and load the Condition
Flag status (CCS(282) and CCL(283)). These can be used to access the sta-
tus of the Condition Flags at other locations in a task or in a different task.
The following example shows how the Equals Flag is used at a different loca-
tion in the same task.

The Clock Pulses are flags that are turned ON and OFF at regular intervals by
the system.
