Abstract:
1. A circuit, comprising: a first control register to be loadable after the circuit is reset, the first control resister to store data that describes an operational mode of the circuit; a first plurality of control registers to be loadable during an initialization process after the circuit is reset and to be unloadable until the circuit is reset again, the first plurality of control registers to store sensitive data based on different operational modes of the circuit; and a first switch unit coupled to the first control register and the first plurality of control registers, wherein the first switch unit to output sensitive data stored by one control register of the first plurality of control registers based on the data loaded in the first control register and to output sensitive data stored by another control register of the first plurality of control registers based on different data loaded in the first control register, the different data loaded in response to a change in the circuit's operational mode, the sensitive data to be used by a unit coupled to the circuit, the unit to operate in accordance with the sensitive data to prevent damage to the circuit.
