Other Parts Discussed in Thread: SYSBIOS

Hi Champs,

I have a question about Sysbios 6.31.04.27.
 
Are the FP processor configuration registers (FADCR, FAUCR and FMCR) part of the thread status?
That is, are they saved and restored when a context switch occurs, or are they considered as "global" and never
saved?
 
I found no explicit statement about this on manuals.
 
I need to set the FP processor rounding mode (to "round to nearest", that should be the default), and I want to be sure
to avoid impacts on other threads.

Kind regards,
one and zero
