Hi I see when shorting Vbat to ground the CPU stops running. So i assume the CPU will also stop when there is an empty battery connected. The datasheet only has this note : [4] The RTC typically fails when VBAT drops below 1.6 V. So i think this does not mean the CPU itself should stop when vbat is too low. Are there any issues with this ? Johan

VBAT input on LPC2103 CPU stops when too low.
