nrf52810(52832)的掉电重启还是外部唤醒判断例程，如下

if(nrf_power_resetreas_get() & NRF_POWER_RESETREAS_OFF_MASK)//读取是掉电重启还是按键唤醒
{//按键唤醒
if(KEY_POWER_PRESSED)
{
key_smokekey_enable();
}

eStateMachine = E_SM_IDLE;
eStateMachine_pre = E_SM_NONE;
}
else
{//掉电重启
eStateMachine = E_SM_PowerOn;
eStateMachine_pre = E_SM_NONE;
}
