CELF
0
R/W Carrier Extension Loss
Indicates that the carrier extension has been lost in 1-
Gigabit/half-duplex transfer. This means that the sum of
a frame and carrier extension is smaller than
SLOT_TIME (4096 bits).
0: Carrier extension loss has not occurred
1: Carrier extension loss has occurred

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 a frame whose byte size exceeds the
upper limit for the receive frame length 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

R/W PHY-LSI Receive Error
0: PHY-LSI receive error has not been detected
1: PHY-LSI receive error has been detected
