Data Sheet
Packet End
A ‘1’ indicates that with the preceding read to register UA5RXDAT0/
DA5RXDAT0 or UA5RXDAT1/DA5RXDAT1, the last two bytes of the
current packet have been read.
CRC Error
A ‘1’ indicates that the CRC32 of the current packet is erroneous.
Illegal Length
A ‘1’ indicates that the length of the current packet is erroneous, i.e the
number of octets does not match the length field in the AAL5 trailer or
exceeds the maximum supported packet length of 65536 octets.
Maximum Frame Length Exceeded
A ‘1’ indicates that the length of the current packet exceeds the
maximum supported packet length of 65536 octets.
Receive Abort
A ‘1’ indicates that the length field of the current packet is 0, indicating
an aborted or corrupted packet.

This bit field indicates the number of valid octets in registers
UA5RXDAT0 and UA5RXDAT1 or DA5RXDAT0 and DA5RXDAT1
respectively.
