Transmit Retry Over
Indicates that a retry-over condition has occurred
during frame transmission. Total 16 transmission
retries including 15 retries based on the back-off
algorithm are failed after the EtherC transmission
starts.
0: Transmit retry-over condition not detected
1: Transmit retry-over condition detected
Receive Multicast Address Frame
0: Multicast address frame has not been received
1: Multicast address frame has been received
Reserved
These bits are always read as 0. The write value
should always be 0.
Receive Residual-Bit Frame
0: Residual-bit frame has not been received
1: Residual-bit frame has been received
Receive Too-Long Frame
Indicates that the frame more than the number of
receive frame length upper limit set by RFLR of the
EtherC has been received.
0: Too-long frame has not been received
1: Too-long frame has been received
Receive Too-Short Frame
Indicates that a frame of fewer than 64 bytes has
been received.
0: Too-short frame has not been received
1: Too-short frame has been received
PHY Receive Error
0: PHY receive error not detected
1: PHY receive error detected
CRC Error on Received Frame
0: CRC error not detected
1: CRC error detected
