TXOK: Transmit Successful
0: Transmission was aborted.
1: Transmission was successful.
TXLOOR: Type Field Detected
0: Last packet’s type/length field was used as a length.
1: Last packet’s type/length field was used as a type.
TXLCERR: Length Check Error
0: Last packet’s length field matched the actual frame length.
1: Last packet’s length field did not match the actual frame length.
TXCRCER: CRC Error
0: Last packet’s CRC matched the internally generated CRC.
1: Last packet’s CRC did not match the internally generated CRC.
Number of collisions encountered during transmission of the last packet.
Note: This bit field does not overflow and will remain at 1111b (15 collisions) if 15 or more collisions
are encountered.
The most significant 8-bits of the number of bytes in the last transmitted frame. Does not include
bytes transmitted due to collided attempts.
