Hi,All!

I'am using upsd3254 in my system,and I've configured the pc2 as ''SRAM standby voltage input'',and the pc4 as ''standby on indicator'' in PSDsoft express,the 32kB sram is located at 0x2000,A 3.6v battery also has been connected to pc2.All seems OK when system running,when power off,I can see that the pc4 was high,but data in sram seems not be backup.what's wrong with me?pls help me! :-[
