R/W 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

These bits are always read as 0. The write value
should always be 0.

R/W Receive Too-Long Frame
Indicates that the frame more than the number of
receive frame length upper limit set by RFLR has
been received.
0: Too-long frame has not been received
1: Too-long frame has been received
2
RTSF
0
R/W 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
