    The Overrun flag is set when the transfer of data from SCIRXSHF to SCIRD overwrites unread data already in SCIRD.

    The overrun flag can be cleared by:

    1. Setting of the SW nRST bit of SCIGCR1 register
    2. Setting of the RESET bit of SCIGCR0 register
    3. A system reset (nRST, or nPORRST)
    4. Writing a 1 to OE bit of SCIFLG register
    5. Reading the corresponding interrupt offset in SCIINTVECT0/1
