TM4C1294NCPDT: Switch the hibernation module clock source in runtime

Hi,

I am working with the TM4C1294NCPDT and I would like to switch between different clock sources for the hibernation module (external RTC and internal low frequency oscillator) in runtime. However, the only way I have found out is to force a reset of the hibernation module (by removing the power supply and VBAT). Is it possible to change the clock source without reseting the hibernation module or is it possible to reset the hibernation module through software?

Thank you in advance
