Original Abstract Submitted
an integrated circuit (ic) includes an input/output (i/o) interface, first-domain circuitry and second-domain circuitry. the i/o interface is coupled to a first voltage domain and is configurable by a set of control bits. the second-domain circuitry is coupled to a second voltage domain and is configured to generate a bit value for a control bit among the control bits, to generate a multi-bit identifier (id) of the control bit, and to transmit the bit value and the multi-bit id. the first-domain circuitry is coupled to the first voltage domain and is configured to receive the bit value and the multi-bit id, to identify the control bit from the multi-bit id, and to configure the control bit of the i/o interface with the bit value.
