Hardware Functional Overview
integrated power management module incorporates the ACPI 1.0b compliance functions, the
APM 1.2 compliance functions, and the PCI bus power management interface spec. v1.1.
Numerous power-up events and power down events are also supported. 24 general purposed
I/O pins are provided to give an easy to use logic for specific application. In addition, the
SiS962L supports Deeper Sleep power state for Intel Mobile processor. For AMD processor,
the SiS962L use the CPUSTP# signal to reduce processor voltage during C3 and S1 state.
A high bandwidth and mature SiS MuTIOL technology is incorporated to connect SiS645DX
and SiS962L MuTIOL Media I/O together. SiS MuTIOL technology is developed into three
layers, the Multi-threaded I/O Channels Layer delivering 1.2GB bandwidth to connect
embedded DMA Master devices and external PCI masters to interface to Multi-threaded I/O
Channels layer, the Multi-threaded I/O Packet Layer in SiS962L to transfer data w/ 533 MB/s
bandwidth from/to Multi-threaded I/O Channels layer to/from SiS645DX, and the Multi-
threaded I/O Packet Layer in SiS645DX to transfer data w/ 533 MB/s from/to memory sub-
system to/from the Multi-threaded I/O Packet Layer in SiS962L.
The SiS 962L MuTIOL Media I/O functions and capabilities include:
