1.8V, Power used by PLL
Descriptions
EEPROM Data Output. Serial data input from EEPROM.
This pin is internally pull-up.
EEPROM Chip Select. This pin is active high chip enable
for EEPROM. When RESETL is low, it will be Tri-state.
Internally Pull-down
Serial Clock. This pin is clock source for EEPROM. When
RESETL is low, it will be tri-state.
Setting
XOVEN: This pin is internal pull-down. On power-on-reset,
latched as P4~0 Auto MDIX enable or not.
“0” to disable MDIX ( defaulted ), “1” to enable MDIX.
Suggest externally pull up to enable MDIX for all ports.
EEPROM Serial Data Input. This pin is output for serial
data transfer. When RESETL is low, it will be tri-state.
Setting
LEDMODE: This pin is internal pull-down. On power-on-
reset, latched as Dual Color mode or not.
“0” to set Single color mode for LED.
“1” to set Dual Color mode for LED.
