摘要
A device may comprise data storage, a power manager and a bridge device that is coupled to the data storage and to the power manager, and configured to bridge between at least a first data protocol and at least a second data protocol. The bridge device may comprise a UART, a first clock, a second clock and bridge device firmware configured to cause the bridge device to selectively configure the UART for communication using the first clock or the second clock. The power manager may be configured to, when a command is to be issued to the data storage when the bridge device firmware has configured the UART for communication using the first clock, assert a signal that causes the bridge device firmware to stop configuring the UART for communication using the first clock and to configure the UART for communication using the second clock.
