Clock Pulses

Saving and Loading Condition Flag Status

4-19 Clock Pulses

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 specified with symbols rather than addresses.
Note The CX-Programmer treats condition flags as global symbols beginning with
P_.
Stores result of comparison in the Condition Flags.
This will enable loading the results to use with
Instruction B.

The result of the comparison instruction in the

interference from Instruction A.
