Dear NXP:


     My chip is lpc54608s512 ,  it's a strange phenomenon ; The MCU works normal for a lot of days, but one day, it can't works after power up , and need power up twice then it works well too;  If the two power up interval too long ,it's can't  works too;

      Do you know what's the matter with the MCU?
