A device and method for generating interrupts to a central processing unit (CPU) for an universal serial bus (USB) keyboard and an USB mouse so that an operating system will treat these interrupts as if caused by an IBM&trade; personal computer series (PS/2) keyboard and PS/2 mouse. An interrupt request (IRQ) register having a first bit and a second bit is used to trigger the interrupts. A first merge unit acting as an OR circuit is connected to the first bit of the IRQ register to generate an interrupt to the CPU when the first bit is set to one. A second merge unit also acting as an OR circuit is connected to the second bit of the IRQ register to generate an interrupt to the CPU when the second bit is set to one.

Device and method to emulate interrupts to provide PS/2 mouse and keyboard functionality for a USB mouse keyboard

A microprocessor system includes a microprocessor and a first controller. The first controller is coupled to the microprocessor, and the first controller includes a first memory adapted to store a power loss indicator. A method for detecting a reduction of a power supply voltage in a microprocessor system includes coupling the power supply voltage to a first memory of a controller. A power loss indicator is stored in the first memory. The occurrence of a predetermined event is detected, and the first memory is read in response to the predetermined event to determine if the power loss indicator is intact.

Method and apparatus for detecting supply power loss

A non-intrusive socket may be used to mount an electrical component such as a surface mount device (SMD) to a board such as a fabricated motherboard. The socket includes a plurality of legs attachable to and detachable from the board. The socket also includes a body contacting with the electrical component and applying a force to the electrical component such that a plurality of electrical leads of the electrical component directly contact a plurality of electrical contact pads formed on the board.
