R/W Description
8 TRO 0 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
7 RMAF 0 R/W Receive Multicast Address Frame
0: Multicast address frame has not been received
1: Multicast address frame has been received
6, 5  All 0 R Reserved
These bits are always read as 0. The initial value
should not be changed.
4 RRF 0 R/W Receive Residual-Bit Frame
0: Residual-bit frame has not been received
1: Residual-bit frame has been received
3 RTLF 0 R/W 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
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
1 PRE 0 R/W PHY Receive Error
0: PHY receive error not detected
1: PHY receive error detected
0 CERF 0 R/W CRC Error on Received Frame
0: CRC error not detected
1: CRC error detected
