ABSTRACT:
Initial data and/or control bits of registers within a digital integrated circuit are loaded from a non-volatile and/or read-only memory provided as part of the circuit. Such loading is accomplished each time the circuit is initialized, such as when power is first turned on to a system in which the circuit is a part. An important use of this technique is with a computer peripheral circuit chip such as a serial communications controller.
