FUNCTION

18

INt

System clock input. According to the input frequency 24MHz or

48MHz, it is selectable through register. Default is 24MHz input.

19

OD8 erated P

21

INtsp3 PCI 33 MHz clock input.

22 OUT12tp3 Encoded DMA Request signal.

23 I/OD12tp3 Serial IRQ input/Output.

24-27

I/O12tp3

These signal lines communicate address, control, and data

information over the LPC bus between a host and a peripheral.

29

INtsp3 Indicates start of a new cycle or termination of a broken cycle.

30

INtsp3 Reset signal. It can connect to PCIRST# signal on the host.
