EEPROM data in

(To be connected to the external EEPROM’s DO pin).

When the optional serial EEPROM is connected, this pin

should be pulled up using an external 1-10k resistor. When

the external EEPROM is not required, this external pull-up is

not necessary as the internal pull-up is sufficient.

EEPROM data out.

(To be connected to the external EEPROM’s DI pin)

TESTPIN.

This must be connected to GND.

MODE selector.

MODE0 = 0. Device operates as a dual function device,

where function 0 is the Dual UARTs and Function 1 is the

parallel port.

MODE0 = 1. Device operates only as a single function

device, where function 0 is the Dual UARTs. Function 1 does

not exist, so the parallel port is not visible2 to PCI accesses.
