•Intruder Detect. The Intel 3420 provides an input signal (INTRUDER#) that can be attached to a switch that is activated by the system case being opened. The Intel 3420 can be programmed to generate an SMI# or TCO interrupt due to an active INTRUDER# signal.
8.17 System Management Bus (SMBus 2.0)
The Intel 3420 contains an SMBus Host interface that allows the processor to communicate with SMBus slaves. This interface is compatible with most I2C devices. Special I2C commands are implemented.
The Intel 3420’s SMBus host controller provides a mechanism for the processor to initiate communications with SMBus peripherals (slaves). Also, the Intel 3420 supports slave functionality, including the Host Notify protocol. Hence, the host controller supports eight command protocols of the SMBus interface (see System Management Bus
(SMBus) Specification, Version 2.0): Quick Command, Send Byte, Receive Byte, Write Byte/Word, Read Byte/Word, Process Call, Block Read/Write, and Host Notify.
