Description
E-MAC-0 Residual-Bit Frame Receive
Set to 1 when a frame containing residual bits (less
than an 8-bit unit) is received in the E-MAC-0.
E-MAC-0 Too-Long Frame Receive
Set to 1 when a frame exceeding the value set by
RFLR0 is received in the E-MAC-0.
E-MAC-0 Too-Short Frame Receive
Set to 1 when a frame with a length of less than 64
bytes is received in the E-MAC-0.
E-MAC-0 Frame Receive Error
Set to 1 when a receive error is detected on the
ET0_RX-ER pin input from the PHY-LSI in the E-MAC-
0.
E-MAC-0 CRC Error Frame Receive
Set to 1 when a receive frame results in a CRC error in
the E-MAC-0.
Reserved
These bits are always read as 0. The write value should
always be 0.
Port 1-to-0 Relay FIFO Overflow Detect
Set to 1 when the port 1-to-0 relay FIFO overflows.
E-MAC-1 Overflow Alert Signal Output
Set to 1 when the threshold of TSU_BSYSL1 is valid
and exceeded.
E-MAC-1 Carrier Extension Loss Error Detect
Set to 1 when a frame with the carrier extension lost is
received in the E-MAC-1.
E-MAC-1 Residual-Bit Frame Receive
Set to 1 when a frame containing residual bits (less
than an 8-bit unit) is received in the E-MAC-1.
E-MAC-1 Too-Long Frame Receive
Set to 1 when a frame exceeding the value set by
RFLR1 is received in the E-MAC-1.
