PIO_PCRHR and it is not read before a new data is stored in PIO_PCRHR, then an overrun
error occurs. The previous data is lost and the OVRE flag in PIO_PCISR is set to 1. This flag is
automatically reset when PIO_PCISR is read (reset after read).
The flags DRDY, OVRE, ENDRX and RXBUFF can be a source of the PIO interrupt.
