In order to read received frames from RXQ without error, the software driver must use following steps:
1.
When receive interrupt occurred and software driver writes “1” to clear the RX interrupt in ISR register; the
KSZ8851 will update Receive Frame Counter (RXFCTR) Register for this interrupt.
2.
When software driver reads back Receive Frame Count (RXFCTR) Register; the KSZ8851 will update both
Receive Frame Header Status and Byte Count Registers (RXFHSR/RXFHBCR).
3.
When software driver reads back both Receive Frame Header Status and Byte Count Registers
(RXFHSR/RXFHBCR); the KSZ8851 will update next receive frame header status and byte count registers
(RXFHSR/RXFHBCR).
EEPROM Interface
It is optional in the KSZ8851SNL to use an external EEPROM. The EED_IO (pin 6) must be pulled high to use external
EEPROM otherwise this pin pulled low or floating without EEPROM.
An external serial EEPROM with a standard microwire bus interface is used for non-volatile storage of information such as
the host MAC address. The KSZ8851SNL 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 must be organized as 16-bit mode.
If the EED_IO pin is pulled high, then the KSZ8851SNL performs an automatic read of the external EEPROM words 0H to
3H 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 (0x22) registers.
The KSZ8851SNL EEPROM format is given in Table 12.
