Description
Interrupt 9 Request Input. Active high.

Note:
Description
LPC Address-Data. Multiplexed command,
address, bidirectional data, and cycle status.
LPC DMA Request. Encoded DMA request
for LPC interface.
Note:
LPC Frame. A low pulse indicates the begin-
ning of a new LPC cycle or termination of a
broken cycle.
LPC Power-Down. Signals the LPC device
to prepare for power shut-down on the LPC
interface.
Serial IRQ. The interrupt requests are serial-
ized over a single signal, where each IRQ
level is delivered during a designated time
slot.
Note:
If IRQ9 function is selected but not
used, tie IRQ9 low.
If IOCHRDY function is selected but
not used, tie IOCHRDY high.
If LDRQ# function is selected but not
used, tie LDRQ# high.
If SERIRQ function is selected but
not used, tie SERIRQ high.
