When looking at instructions from help, instruction reference,CJ/CS. I see flags area. how can i tell what these are?

Like in BCNT.
Top Says Bit Counter
Next part shows symbol
Next is applicable program area

They are described in section 6 of the W473 manual.

so instruction processing error flags are global for all of them. Each condition in the cj2m process share the same ER Flag?

Why would you need an error flag for a bit counter? It would only ever go off if the value went over the maximum and that would be a huge number of bits. It is one of my favourite instructions - saves so much time and programming when used properly.

Hi
The ER, EQ etc flags are valid after the instruction is executed until another instruction is executed when they are refreshed with that instruction's results.
