System clock input, which is selective by the register according
to the input frequency either 24MHz or 48MHz. Default is
48MHz.
Generated PME event.
PCI clock 33 MHz 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.
