Abstract

A method for serial interface clock domain crossing includes identifying a data communication command received over a serial interface. An address is decoded to determine whether the address falls within a direct latch address range of a register bank. Data is communicated over the serial interface. A multiplexed output clock is generated, for writing to and reading from the register bank, based on at least one of a current system operating state and a refresh control signal from a host processor.
