RX_DATA_INTEGRI
TY_ERROR
R
0*, 1
This flag is set to 1, if a data integrity error has been
detected. Possible caused can be a wrong parity or a wrong
CRC.
Note
: On a data integrity error the reception is continued
Note
: The flag is automatically cleared at start of next
reception.
Note
: If a reversed parity bit is a stop criteria, the flag is not
set to 1 in case of a wrong parity.

RX_NUM_LAST_BIT
S
R
0* - 7h
Defines the number of valid bits of the last data byte
received in bit-oriented communications. If zero, the whole
byte is valid.
12:9
RX_NUM_FRAMES_
RECEIVED
R
0* - 8h
Indicates the number of frames received. The value is
updated when the RxIRQ is raised.
Note
: This bit field is only valid when the RxMultiple is active
(bit RX_MULTIPLE_ENABLE set)
8:0
RX_NUM_BYTES_R
ECEIVED
R
0* - 104h
Indicates the number of bytes received. The value is valid
when the RxIRQ is raised until the receiver is enabled again.
