Receive Overrun Register (ROVRR)
If RCx of the reception complete register (RCR) is "1" when completing storing of a
received message in the message buffer (x), ROVRx becomes "1", indicating that
reception has overrun.

Receive Overrun Register (ROVRR)
Figure 23.6-19 Configuration of the Receive Overrun Register (ROVRR)
[bit15 to bit0] ROVR15 to ROVR0:
Writing "0" to ROVRx results in ROVRx = 0. Writing "1" to ROVRx is ignored. After checking that
reception has overrun, write "0" to ROVRx to set it to "0".
"1" is read when a Read Modify Write (RMW) instruction is performed.
Note:
If setting to "1" by completion of the receive operation and clearing to "0" by writing occur at the
same time, the bit is set to "1".
