Hi,
Currently we have done
1) All ports made as Digital input with pullup or pull down enabled.
2) Left Unified Clock System and Voltage core in the recent settings before going to LPM3
3) RTC is running in counter mode with interrupt enabled to wake up after some time.
4) No other internal modules like I2C,ADC, etc. are running/enabled.
Please let us know whether there are any other measures we can take to reduce current consumption in LPM3 mode.
Thanks,
Ayyappan M.
