Re: which rom400_task routines are safe to call from an isr

I was hoping to get better performance than this

I want to use this in a case where I get an interrupt
every 2-3 milliseconds which then requires about 1-2
milliseconds of processing.  While the processing is
happening I do not want to miss other interrupts.

polling every 4ms means my performance will drop to
roughly half.

any suggestions?
