A method of communicating with an embedded controller is disclosed. The method is adapted for an Advanced Configuration and Power Interface specification (ACPI). According to the method, a busy flag is set in the status register of the embedded controller. While the Operating System Power Management handler (OSPM) accesses the embedded controller, the busy flag is set with a busy state value. When the OSPM finishes accessing the embedded controller, the busy flag is set with a non-busy state value.
