System clock input. According to the input frequency 24MHz or
48MHz, it is selectable through register. Default is 24MHz in-
put.
Generated PME event.
PCI clock input.
Encoded DMA Request signal.
Serial IRQ input/Output.
These signal lines communicate address, control, and data in-
formation over the LPC bus between a host and a peripheral.
Indicates start of a new cycle or termination of a broken cycle.
Reset signal. It can connect to PCIRST# signal on the host.
