Possibly. That would require defining a format for the reset specifier, which we haven't done yet (one or two numbers?). There can be multiple reset registers, handling multiple CPU cores each, depending on the SoC. For now we're interested in the mode monitoring feature only, for obtaining the values of the boot mode pins.
