ABSTRACT:
An in-circuit emulation unit with a probe implemented on a microprocessor whilst in emulation upon entering or leaving system management mode. The present invention is used on a microprocessor in a target computer system. The present invention offers the ability to implement a capability where a user could access emulation information while a system is in or out of system management mode. The present invention provides a better way of controlling a target computer system when in system management mode thereby allowing user access to special system management code, processor contents, processor registers and system state variables necessary for debug and design of system management features available on todays laptop and desktop computers.
