21.4.19 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.
■ Register Configuration
Figure 21.4-19 Configuration of the Receive overrun Register (ROVRR)
■ Register Function
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 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.
