STM32F100RB External Powerup

Hello,
I am attempting to power the STM32F100RB from a battery pack, however I am unsure what needs to happen in order for this to work and the datasheet has been vague/confusing (or I'm missing something). I at first thought I would just need to power either the VBAT/3.3V/5V inputs, however I cannot find any documentation that supports this train of thought. If possible I would like to know what pins and at what voltages are required to have the STM32F100RB Value Line Discovery board running off of a battery.
