翻译Low-power mode (LPM) is used to reduce system quiescent currents. Low-power mode may be entered only by sending the Low-power command. When returning to Normal mode, all register settings is maintained. The Enter Low-power mode register is write only and has the effect of going to LPM and beginning operation as selected (polling, interrupt timer). When returning form Low-power mode, the first SPI transaction will return the Fault Status and the intflg bit set to high, as well as the actual status of the Input pins.

低功耗模式（LPM）用于降低系统静态电流。只能通过发送低功耗命令进入低功耗模式。返回到正常模式时，所有寄存器设置将被保留。
进入低功耗模式寄存器只能写入，并且具有进入所选的LPM和开始操作（轮询、中断计时器）的效果。从低功耗模式返回时，第一个SPI事务将返回故障状态和intflg位设置为高，以及输入引脚的实际状态。
