ABSTRACT:
A circuit and method are provided enabling the transfer of signals from a first voltage domain to a second voltage domain. The circuit comprises level shifters enabling the signal transfer, and is space-efficient and power efficient. A 3-wire serial protocol is used to enable the serial transmission of signals across the voltage domain boundary, and provides two distinct reset states.
