Applicable Program Areas
Description
Saves the current status of the Condition Flags in a separate area within the
CPU Unit. The current status of the Flags is preserved so that it can be read
(restored) with CCL(283) at a different location in the program, in a different
task, or even in a later cycle.
This instruction is supported by the CS1-H, CJ1-H, CJ1M, and CS1D CPU
Units only.

When the execution condition is ON, CCS(282) stores the current status of
the Condition Flags (except for the ALWAYS ON and ALWAYS OFF Flags) in
a separate area in the CPU Unit. The Status of the following Condition Flags
will be preserved: ER, CY, >, =, <, N, OF, UF, >=, <>, and <=.
The preserved status of the Condition Flags can be read (restored) later only
with CCL(283), the LOAD CONDITION FLAGS instruction. The status can be
read in any of the following cases:
• Within a task
• Between different cyclic tasks
• Between cycles
