CC2541关于PM2低功耗模式

Question

用3.2V，5mA的电源驱动CC2541能否进入正常工作？是否是直接进入PM2低功耗模式了，那此时ADC转换以及定时器Timer3以及中断是否都不可以用了
求大神解答

Answer 1

可以正常工作，低功耗部分的程序基本不用改就可以用了，但是要注意一下引入低功耗的条件，Datasheet 里都有，
PM2 模式是可以用外部中断唤醒的

PM2 has the second-lowest power consumption. In PM2, the power-on reset, external interrupts, selected
32-kHz oscillator, and Sleep Timer peripherals are active. I/O pins retain the I/O mode and output value
set before entering PM2. All other internal circuits are powered down. The voltage regulator is also turned
off. When PM2 is entered, a power-down sequence is run.
