Abstract
A method for configuring a program-controlled integrated circuit which contains default configuration data and includes input/output lines connectable to at least one external source of configuration data, the method including: a) determining whether an external source of configuration data is connected to the input/output lines; b) in response to a determination that an external source of configuration data is connected to the input/output lines, configuring the integrated circuit in accordance with that configuration data from that source; and c) in response to a determination that an external source of configuration data is not connected to the input/output lines, configuring the integrated circuit in accordance with the default configuration data. An application specific integrated circuit containing circuit units which must be configured in accordance with configuration data, the circuit including: external connection lines for connecting the circuit to an external source of configuration data; a first non-volatile memory portion storing default configuration data; and a second non-volatile memory portion storing a control program which is operative for selecting configuration data from among configuration data stored in a connected external source connected to the external connection lines and the stored default configuration data.
