一个芯片数据手册上的一句英语翻译

Question

Cortex-M3 LPC1766芯片数据手册上的一段英文：
To optimize power conservation, the user has the additional option of turning off or
retaining power to the 32 kHz oscillator. It is also possible to use external circuitry to turn
off power to the on-chip regulator via the VDD(REG)(3V3) pins after entering Deep
Power-down mode.Power to the on-chip regulator must be restored before device
operation can be restarted.其中的第二句：
It is also possible to use external circuitry to turn
off power to the on-chip regulator via the VDD(REG)(3V3) pins after entering Deep
Power-down mode.好拗口呀！！做何解释呢？谢谢。

Answer 1

为了保护有效能源………………。在进入深掉电模式之后，通过电源引脚(REG)(3V3)我们可以使用外部电路关上调整器芯片这一方法是可行的。
