Hi,
I'm trying to speed up iicbb by switching from DELAY to something with a =
higher resolution. I figured I'd try to use the time-honored method of =
calibrating an I/O operation as a delay loop. To my surprise, =
{get,}{micro,nano}uptime dont seem to be ticking during boot.
Am I doing something wrong? Is there an easier way to get a =
sub-microsecond delay?
Stefan
