Abstract
An environment monitoring integrated circuit is provided that allows the boundaries of operating parameters to be conveniently modified. The present invention allows the hardware designer to easily change the temperature boundary of the computer operation, or the boundaries of the operating voltage, the operating temperature and the rotation speed of the fan. The present invention uses limit registers which provide a simple implementation for changing the boundaries of the operating parameters of the computer.
