System clock input. According to the input frequency 24MHz or
48MHz, it is selectable through register. Default is 24MHz input.
Generated PME event.
PCI clock input.
Encoded DMA Request signal.
Serial IRQ input/Output.
These signal lines communicate address, control, and data
information 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.
