nrf52810(52832)的掉電重啟還是外部喚醒判斷例程，如下

if(nrf_power_resetreas_get() & NRF_POWER_RESETREAS_OFF_MASK)//讀取是掉電重啟還是按鍵喚醒
{//按鍵喚醒
if(KEY_POWER_PRESSED)
{
key_smokekey_enable();
}

eStateMachine = E_SM_IDLE;
eStateMachine_pre = E_SM_NONE;
}
else
{//掉電重啟
eStateMachine = E_SM_PowerOn;
eStateMachine_pre = E_SM_NONE;
}
