Rev. 1.0

Note: This register contains bits 23–16 of the Transmit Status Vector.

Bit 7:

TXOK: Transmit Successful

0: Transmission was aborted.

1: Transmission was successful.

Bit 6:

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.

Bit 5:

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.

Bit 4:

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.

Bits 3–0: TXCOL3-0: Transmit Collision Count

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.
