翻译这段英语并把里面用到的语法讲解一下In Polling mode, the HAL functions return the process status when the data processing in blocking mode is complete. The operation is considered complete when the function returns the HAL_OK status, otherwise an error status is returned. The user can get more information through the HAL_PPP_GetState() function. The data processing is handled internally in a loop. A timeout (expressed in ms) is used to prevent process hanging. The example below shows the typical Polling mode processing sequence :

在轮询模式下，当阻塞模式中的数据处理完成时，HAL函数会返回进程状态。当函数返回HAL_OK状态时，操作被认为是完成的，否则将返回错误状态。用户可以通过HAL_PPP_GetState()函数获取更多信息。数据处理在内部循环中处理。超时时间（以毫秒为单位）用于防止进程挂起。下面的示例显示了典型的轮询模式处理序列：

这段英语中使用了一些技术语言和特定的语法结构，其中包括：

1. 介词短语"in Polling mode"表示在轮询模式下；
2. 从句"when the data processing in blocking mode is complete"表示当阻塞模式的数据处理完成时；
3. 主语"the operation"表示操作；
4. 从句"otherwise an error status is returned"表示否则返回错误状态；
5. 动词短语"get more information"表示获取更多信息；
6. 名词短语"the data processing"表示数据处理；
7. 介词短语"in a loop"表示在循环中；
8. 名词短语"a timeout"表示超时时间；
9. 动词短语"prevent process hanging"表示防止进程挂起；
10. 名词短语"the typical Polling mode processing sequence"表示典型的轮询模式处理序列。

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。

翻译The wake-up register defines the inputs that are allowed to wake the 33978 from Low-power mode. Programming the wake-up bit to logic [0] disables the specific input from waking the IC (Table 29). Programming the wake-up bit to logic [1] enables the specific input to wake-up with any switch change of state The MCU may change or update the wake-up register via software at any time in Normal mode. The Wake-up register defaults to logic [1] (wake-up enabled). If all channels (SG and SB) have the Wake-up bit disabled, the device disables the polling timer to reduce the current consumption during Low-power mode.

唤醒寄存器定义了可以从低功耗模式唤醒33978的输入信号。将唤醒位编程为逻辑[0]会禁用特定输入信号唤醒IC（表29）。将唤醒位编程为逻辑[1]会启用特定输入信号，以便在任何开关状态改变时唤醒。MCU可以在正常模式下随时通过软件更改或更新唤醒寄存器。唤醒寄存器默认为逻辑[1]（启用唤醒）。如果所有通道（SG和SB）的唤醒位被禁用，设备将禁用轮询定时器，以减少低功耗模式下的电流消耗。
