This pin is driven by the EEDO output of the
external EEPROM.
This pin drives the EEDI input of the external
EEPROM.
This pin drives the chip select output of the external
EEPROM.
This pin drives the EEPROM clock of the external
EEPROM.
This active low pin functions as the JTAG test port
reset input.
Note:
This pin functions as the JTAG test mode select.
This pin functions as the JTAG data input.
This pin functions as the JTAG data output.
This pin functions as the JTAG test clock.
This active low pin allows external hardware to
reset the device.
Note:
This pin is driven low (LED on) when the Ethernet
link is operating in full-duplex mode.
This General Purpose I/O pin is fully programmable
as either a push-pull output, an open-drain output,
or a Schmitt-triggered input.
This pin should be tied high if it is not
used.
This pin should be tied high if it is not
used.
