my project is used nrf51822 mcu, it contains SIM, when the mcu is reading SIM data, and at the same, I take out theSIM, and the 51822's pin which is link with SIM is can't control,the IO is unnormal.
1、turn off the power, it recover
2、send command to 51822 by nus service ,then 51822 do NVIC_SystemReset();,then it recover
