This pin is internally pulled to GND.
See MSEL 0 above. This pin is internally pulled to GND.
See MSEL 0 above. This pin is internally pulled to GND.
External EEPROM Chip Select (Active high).
This pin enables the External EEPROM to load the
Ethernet confi guration data.
External EEPROM clock (<1 MHz).
Data output from MCS7830 to external EEPROM.
Ethernet MAC will use this pin to serially write op codes
and addresses into the serial EEPROM.
Data output from external EEPROM to MCS7830.
Ehternet MAC will read the contents of the EEPROM
serially through this pin.
System (USB) reset (active low).
Crystal, or External USB-2.0 Clock Input. (12/30 MHz)
Crystal Output.
XTALA Crystal Clock Select Pin (Internal Pull-Down).
0 = 12 MHz Clock, 1 = 30 MHz Clock.
USB PHY Reference Signal.
External resistor to GND is required.
USB-2.0 PHY Data Minus pin.
USB-2.0 PHY Data Plus pin.
Twisted-Pair Input (RXIN, RXIP). Differential input pair
for either 100 BASE-TX or 10 BASE-T reception.
See RXIN.
10/100 Ethernet PHY Transmit Reference.
Connected to Analog Ground through resistor
10/100 Ethernet PHY 25 MHz Crystal Clock Input.
Crystal Output.
Twisted-Pair Output (TXON, TXOP), Differential driver
pair for Ethernet PHY 100 BASE-TX or 10 BASE-T
transmission.
See TXON.
This pin can be used to initiate a host wake-up form the
suspend state. Refer to the application schematic for
system interface details.
