CCS
There are no flags affected.
CCL
Changes to the value that was read.
Function
CCS
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 <=.
Note When CCS(282) is executed, it overwrites the previous Condition Flag information that was saved.
CCL
When the execution condition is ON, CCL(283) restores (reads) the status of the Condition Flags
(except for the ALWAYS ON and ALWAYS OFF Flags). The Status of the following Condition Flags will
be restored (read): 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
