I/O
MIO 0
Multi-purpose I/O 0. Can be driven high or low, or be used to
assert PCI interrupts or power management events (PME).
Multi-purpose I/O 1. Can be driven high or low, or be used to
assert PCI interrupts or power management events (PME).

EEPROMdata in
(To be connected to the external EEPROMs DO pin).
When the optional serial EEPROMis 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.

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 visible
