when I decided on the SF_blah standard it was created to a) make global searches show EVERY access to a given SFR and mark the names as SFRs. I doubt that anyone need TMOD marked as an SFR, but the new derivatives have SFRs that I would not recognize as such with a quick glance.

Anyhow to the point, after the standard was established, I decided to use the Cygnal F12x for a project and that chip has SFR pages. so the standard grew to
SFG_blah SFR accessible regardless of page selected
SF0_blah SFR in SFRpage 0
...
SB0_blah SFR bit in SFRpage 0
....

This made the coding of SFR access via proper page a breeze compared to looking up the page every time a SFR were to be accessed.
