Abstract: A method may include receiving signaling at a system basis chip implementing a transceiver of a 10SPE PHY; changing, at the system basis chip, the signaling from first voltage levels incompatible with a voltage domain of a microcontroller (MCU) implementing a controller of the 10SPE PHY to second voltage levels compatible with the voltage domain of the MCU; and communicating the changed signaling to the MCU.

Abstract: An apparatus may include a voltage source, a voltage protection circuit, and a chip powered at least in part via the voltage protection circuit. The chip may include at least one regulated voltage source; and a logic circuit. The logic circuit may determine a state of a supply voltage produced by the voltage protection circuit; determine a state of an input voltage produced by the voltage source; and determine and indicate a predicted state of the supply voltage produced by the voltage protection circuit or a predicted state of the at least one regulated voltage source, in either case at least partially based on the determined state of the supply voltage produced by the voltage protection circuit and the determined state of the input voltage produced by the voltage source.
