Figure 10. KSZ8893FQL EEPROM Configuration Timing Diagram.
The following is a sample procedure for programming the KSZ8893FQL with a pre-configured EEPROM:
1. Connect the KSZ8893FQL to the EEPROM by joining the SCL and SDA signals of the respective devices. For
the KSZ8893FQL, SCL is pin 97 and SDA is pin 98.
2. Enable I
2C master mode by setting the KSZ8893FQL strap-in pins, PS[1:0] (pins 100 and 101, respectively) to
“00”.
3. Check to ensure that the KSZ8893FQL reset signal input, RST_N (pin 67), is properly connected to the external
reset source at the board level.
4. Program the desired configuration data into the EEPROM.
5. Place the EEPROM on the board and power up the board.
6. Assert an active-low reset to the RST_N pin of the KSZ8893FQL. After reset is de-asserted, the KSZ8893FQL
begins reading the configuration data from the EEPROM. The KSZ8893FQL checks that the first byte read from
the EEPROM is “88”. If this value is correct, EEPROM configuration continues. If not, EEPROM configuration
access is denied and all other data sent from the EEPROM is ignored by the KSZ8893FQL. The configuration
access time (tprgm) is less than 15ms.
Note:
For proper operation, check to ensure that the KSZ8893FQL PWRDN input signal (pin 36) is not asserted during
the reset operation. The PWRDN input is active low.
I2C Slave Serial Bus Configuration
In managed mode, the KSZ8893FQL can be configured as an I
2C slave device. In this mode, an I2C master device
(external controller/CPU) has complete programming access to the KSZ8893FQL’s 142 registers. Programming access
includes the Global Registers, Port Registers, Advanced Control Registers and indirect access to the “Static MAC
Table”, “VLAN Table”, “Dynamic MAC Table,” and “MIB Counters.” The tables and counters are indirectly accessed via
registers 121 to 131.
In I
2C slave mode, the KSZ8893FQL operates like other I2C slave devices. Addressing the KSZ8893FQL’s 8-bit
registers is similar to addressing Atmel’s AT24C02 EEPROM’s memory locations. Details of I
2C read/write operations
and related timing information can be found in the AT24C02 Datasheet.
Two fixed 8-bit device addresses are used to address the KSZ8893FQL in I
2C slave mode. One is for read; the other is
for write. The addresses are as follow:
1011_1111 <read>
1011_1110 <write>
The following is a sample procedure for programming the KSZ8893FQL using the I
2C slave serial bus:
1. Enable I
2C slave mode by setting the KSZ8893FQL strap-in pins PS[1:0] (pins 100 and 101, respectively) to
“01”.
2. Power up the board and assert reset to the KSZ8893FQL. After reset, the “Start Switch” bit (register 1 bit [0]) is
set to ‘0’.
3. Configure the desired register settings in the KSZ8893FQL, using the I
2C write operation.
