Dear All,

     I have a question about LPC1788 RTC's General purpose registers 0-4,   I write 1 to General purpose registers 0 , then power off(without battery powered) , General purpose registers 0 value changed to 0 after power on. 

     the user manual said : These registers can be used to store import information when the main power supply is off .  It seems that General purpose registers can not store information without main power supply & battery power supply?
