On the BS2, each bit takes 60 µsec (clock high 14 µsec, low 46 µsec).

You can't make SHIFTIN/SHIFTOUT work faster. All you can do is
optimize for speed the code that invokes these routines. If you
post your algotithm/code maybe a faster flow could be suggested.

was wondering because i am using the max192 and i need to sample all
eight channels and it doesn't seem to be very fast. Is there anyway
to speed up the signal?
