I,LI EEPROM Data In
The DM9102 will read the contents of EEPROM serially
through this pin.
O EEPROM Data Out
The DM9102 will use this pin to serially write op codes,
addresses and data into the EEPROM.
O EEPROM Serial Clock
This pin provides the clock for the EEPROM data transfer.
O EEPROM Chip Select
This pin will enable the EEPROM during loading of the
Configuration Data.
I TEST option control
This pin are valid only test mode enabled.
In normal operation when in multiplex mode, this pin
are pulled low.
I TEST option control
These two pins are valid only test mode is enabled.
In normal operation when in multiplex mode, these two
pins are pulled low.
In Multiplex mode, these three pins are not connected.
