Omron CJ1 SSET stack persistence

[JordanCClark]

Hey all,

If I manually set a stack (not using the first scan bit) does the stack persist after an event like a power cycle or download, as long as the data area isn't touched, of course.

Thanks in advance!

When defining the stack with the SSET(630) instruction, the stack information will be stored in the first 4 WORDS. (Last WORD Address and Stack Pointer).

Using memory such as D or H will make these items retentive. Additionally, memory is not overwritten when downloading the program. So yes, it will persist after a power cycle or download.

Thanks for the sanity check.
