IN_tp3 System clock input. According to the input frequency 24MHz or
48MHz, it is selectable through register. Default is 24MHz input.
98 OD_12p3 Generated PME event.
19 IN_tsp3 PCI clock 33 MHz input.
20 O_12p3 Encoded DMA Request signal.
21 I/O12tp3 Serial IRQ input/Output.
23- I/O_12tp3 These signal lines communicate address, control, and data
26
information over the LPC bus between a host and a peripheral.
27 IN_tsp3 Indicates start of a new cycle or termination of a broken cycle.
28 IN_tsp3 Reset signal. It can connect to PCIRST# signal on the host.
