Description
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).
EEPROM clock signal
EEPROM active-high Chip Select Signal
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 visible
accesses.
