Description
Port 1 LED Indicators:
Default: Link/Act. (refer to register 195 bit[5:4])
Strap option: Port 3 duplex mode selection(P3DPX)
PU = port 3 default to half duplex mode
PD = port 3 default to full duplex mode
Port 2 LED Indicators:
Default: Speed (refer to register 195 bit[5:4])
Strap option: Serial bus configuration
Port 2 LED Indicators:
Default: Link/Act. (refer to register 195 bit[5:4])
Strap option: Serial bus configuration
Serial bus configuration pins to select mode of access to
KSZ8873MLL/FLL/RLL internal registers.
[P2LED1, P2LED0] = [0, 0] — I
(If EEPROM is not detected, the KSZ8873MLL/FLL/RLL will be
configured with the default values of its internal registers and the values
of its strap-in pins.)
[P2LED1, P2LED0] = [0, 1] — I
The external I
The KSZ8873MLL/FLL/RLL device addresses are:
1011_1111
1011_1110
[P2LED1, P2LED0] = [1, 0] — SPI slave mode
[P2LED1, P2LED0] = [1, 1] – SMI/MIIM-mode
In SMI mode, the KSZ8873MLL/FLL/RLL provides access to all its
internal 8-bit registers through its SCL_MDC and SDA_MDIO pins.
In MIIM mode, the KSZ8873MLL/FLL/RLL provides access to its 16-bit
MIIM registers through its SDC_MDC and SDA_MDIO pins.
