Table 2: Pin Descriptions
Description
Subsystem ID. After reset the subsystem ID of Function 0
will default to the value assigned to these pins
Subsystem Vendor ID. After reset the subsystem vendor ID
of Function 0 will default to the value assigned to these pins.
Multi-purpose I/O 0. Can drive high or low, or assert a PCI
interrupt
Permanent high impedance
Multi-purpose I/O 1. Can drive high or low, or assert a PCI
interrupt
Permanent high-impedance when LCC[6:5] ‘00’
Multi-purpose I/O 2. When LCC[7] = 0, this pin can drive high
or low, or assert a PCI interrupt.
Input power management event. When LCC[7] is set this
input pin can assert a function 1 PME#
Multi-purpose I/O pins. Can drive high or low, or assert a PCI
interrupt
EEPROM clock
EEPROM active-high Chip Select
EEPROM data in. When the serial EEPROM is connected,
this pin should be pulled up using 1-10k resistor. When the
EEPROM is not used the internal pullup is sufficient.
EEPROM data out.
Must be connected to GND
Mode selector:
00: Function 0 is Quad UART, Function 1 is 8-bit local bus
01: Function 0 is Quad UART, Function 1 is parallel port
10: Function 0 is Quad UART, Function 1 is unusable as the
local bus pins are used to assign Subsystem ID and
Subsystem Vendor ID to function 0
11: Function 0 is unusable, Function 1 is 32-bit local bus
Supplies power to output buffers in switching (AC) state
Power supply. Supplies power to core logic, input buffers
and output buffers in steady state
Supplies GND to output buffers in switching (AC) state
Ground (0 volts). Supplies GND to core logic, input buffers
and output buffers in steady state
