Description
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.
Defines the number of valid bits of the last data byte
received in bit-oriented communications. If zero, the whole
byte is valid.
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)
Indicates the number of bytes received. The value is valid
when the RxIRQ is raised until the receiver is enabled again.
Description
Arbitrary preset value for the Rx-Decoder CRC calculation.
Reserved
Preset value of the CRC register for the Rx-Decoder. For a
CRC calculation using 5-bits, only the LSByte is used.
0000h, reset value
Note: That this configuration is set by the Mode detector for
FeliCa.

Note: That this configuration is set by the Mode detector for
ISO14443 type A.

Note: That this configuration is set by the Mode detector for
ISO14443 type B.
