6.2.5 Illegal Frames
During the receiving process, the MAC will monitor the length of the received frame. Illegal frames such as a bad
CRC packet, runt packet (less than 64 bytes) or oversized packet (greater than 1536) will be discarded.
If the carrier sense (CRS) signal in the RMII interface is asserted and RXD[1:0] at the beginning of the packet is
‘10’, the port is considered to have a false carrier event. Normal carrier has a preamble value of ‘01’. The false
carrier event is recorded for the MIB counter.
The RTL8308B can handle frames up to 1536 bytes. All frames longer than 1536 byte will be discarded. If the port
continues to receive data after the 1536th byte, the port’s data will be filtered. If the port is in half duplex mode, the
port will no longer be able to transmit or receive data during the long packet reception.
6.3 EEPROM Interface
The serial EEPROM interface is designed to load information required by various optional functions. The interface
implements the SDA signal and it is directly compatible with the 93C46 device. The controller reads, in serial
format, in the first 272 bits (seventeen 16-bit words) out of the EEPROM and stores them in registers. Because the
information stored in EEPROM is static, this read occurs only on power-up. The serial EEPROM shifts out the
most significant bit of the word first.
