Description
I/O
When RST is inactive these pins can be used to access external
memory. When RST is active configuration is loaded with the data
value on MD0-MD7 pins.
When RST is inactive These pins drive the memory address bus
during DMA access cycle. When RST is active configuration is loaded
with the data value on MA0-MA13 pins.
Memory Bus Read: Strobes data from the buffer memory into the
EPCC via the memory data bus.
Memory Bus Write: Strobes data from the EPCC into the external
buffer memory via the memory data bus.
Buffer RAM chip select, active low.
EEPROM chip select. It is asserted when to access EEPROM.
Connected to EEPROM data output pin.
Connected to EEPROM data input pin.

10BaseT differential transmit drivers.
10BaseT wave predistortion control differential outputs.
10BaseT differential receive input port.
Filter input for data recover analog PLL.
Link integral LED driver. During Link loss, output high.
During loading EEPROM data, used as Serial clock to the EEPROM.
When power on reset, This pin must stay at high level. Otherwise,
TC3299A will enter internal test mode.
Active LED:(default) MA8 is open, when power reset. It functions as
active indication LED driver.
CLED: MA8 pull down during power reset. It works as Collision LED
driver.
