* On v1 interrupts cannot be cleared individually.
Instead they are cleared implicitly by reading or writing DR (which we do now).
* Multiple error flags can be set at the same time:
Handle them all in one go intstead of re-entering the ISR for each one so that
we do not lose any error flags on v1 hardware.
* Wake when the RX buffer becomes full: This allows fast running chips to pull data
from the buffer before receiving the next byte.
