LPC Clock: These signals are
the clocks driven by the
processor to the LPC devices.
Each clock can support up to
two loads.
Note:
If the primary boot
device is connected
via the LPC interface,
it uses
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_CLKOUT1 interface
is not used, the signals can be
used as GPIO Port 27.

Clock Run: (active low). Bi-
directional signal that gates
the operation of the
LPC_CLKOUTx. Once an
interrupt sequence has
started, LPC_CLKRUN_B
remains asserted to allow the
LPC_CLKOUTx to run. If the
LPC_CLKRUNB interface is not
used, the signals can be used
as GPIO Port 28.

Serial Interrupt Request: This
pin conveys the serial
interrupt protocol. If the
ILB_SERIRQ interface is not
used, the signals can be used
as GPIO Port 29.
