[P2LED1, P2LED0] = [0, 0] — I2C Master (EEPROM) mode
45 P2LED1 Ipu/O (If EEPROM is not detected, the KSZ8863MLL/FLL/RLL is configured with the default values of its internal registers and the values of its strap-in pins.)
Interface Signals Type Description
SPIQ O Not used (tri-stated) SCL_MDC O I2C clock SDA_MDIO I/O I2C data I/O SPISN I Not used
[P2LED1, P2LED0] = [0, 1] — I2C Slave mode
The external I2C Master drives the SCL_MDC clock. The KSZ8863MLL/FLL/RLL device addresses are: 1011_1111 <read> 1011_1110 <write>
