In embodiments, such a component may include a number of control pins including a clock pin, a number of data pins, and a logic unit. The logic unit may be configured to receive a clock signal from another component through the clock pin, to provide an alert signal to the other component through a selected one of the control and data pins to initiate a transaction with the other component, to receive in response to the alert signal from the other component through the data pins a status request to determine nature of the transaction, and to provide in response to the status request to the other component through the data pins a status to indicate the nature of the transaction. The provision of the alert signal, the receipt of the status request and the provision of the status may be in reference to the clock signal. Other embodiments may be disclosed or claimed.
