Bit
Description
1
RXRF Receive Runt Frame
When set, it indicates that a frame was damaged by a collision or had a premature termination
before the collision window passed.
Runt frames are passed to the host only if the pass bad frame bit is set.
0
RXCE Receive CRC Error
When set, it indicates that a CRC error has occurred on the current received frame.
CRC error frames are passed to the host only if the pass bad frame bit is set.

EEPROM Interface
It is optional in the KSZ8841M to use an external EEPROM. In the case that an EEPROM is not used, the EEEN pin must
be tied Low or floating.
An external serial EEPROM with a standard microwire bus interface is used for non-volatile storage of information such as
the host MAC address, base address, and default configuration settings. The KSZ8841M can detect if the EEPROM is a
1KB (93C46) or 4KB (93C66) EEPROM device (the 93C46 and the 93C66 are typical EEPROM devices). The EEPROM
is organized as 16-bit mode.
If the EEEN pin is pulled high, then the KSZ8841M performs an automatic read of the external EEPROM words 0H to 6H
after the de-assertion of Reset. The EEPROM values are placed in certain host-accessible registers. EEPROM read/write
functions can also be performed by software read/writes to the EEPCR registers.
The KSZ8841M EEPROM format is given in Table 9.
