GENERAL DESCRIPTION  
The Am486DE2 microprocessor is an addition to the  
AMD Am486 microprocessor family. The Am486DE2  
enhances system performance by incorporating flexible  
clock control and enhanced SMM.  
The Am486DE2 CPU clock control feature permits the  
CPU to be stopped under controlled conditions, allowing  
reduced power consumption during system inactivity.  
The SMM function is implemented with an industry-stan-  
dard, two-pin interface.
