20K, PU

V3P3S

LPC Address/Data: 

Multiplexed Command, 

Address, Data. If the 

LPC_AD0 interface is not 

used, the signals can be used 

as GPIO Port 21.

LPC_AD1 interface is not 

used, the signals can be used 

as GPIO Port 22.

20K, PU

V3P3S

LPC Address/Data: 

Multiplexed Command, 

Address, Data. If the 

LPC_AD3 interface is not

V3P3S

LPC Frame: (active low). 

Output signal that indicates 

the start of an LPC cycle or an 

abort. 

The LPC controller 

does not implement 

DMA or bus 

mastering cycles. 

If the LPC_FRAMEB interface 

is not used, the signals can be 

used as GPIO Port 25. 

LPC_CLKOUT0/

GPIOS_26

V3P3S

LPC Clock: These signals are 

the clocks driven by the 

processor to the LPC devices. 

Each clock can support up to 

two loads. 

If the primary boot 

device is connected 

via the LPC interface, 

it should use 

LPC_CLKOUT[0]. 

Using the LPC 

interface for the boot 

device is not 

supported at this 

time and may not 

ever be supported by 

this Intel product. 

Only use the SPI 

interface for boot 

device connection. 

If the LPC_CLKOUT0 interface 

is not used, the signals can be 

used as GPIO Port 26.
