How do I shut down VCC_LICELL on the SBC Pro Dev Kit?
I am trying to prevent the coin cell that supplies the RTC (MCA) from supplying other parts of the ConnectCore SBC Pro Dev kit.
My understanding is that the power config of the MCA needs to be changed in order to use the RTC with a coin cell. (Or at least use it with RTC without supplying other parts of SOM.)
Initially I saw errors on startup with the bluetooth when the coin cell was connected, I disabled the bluetooth and no longer see those errors, but I am not sure the coin cell is supplying only the MCA/RTC or if other parts of SOM dev kit are drawing from coin cell because the MCA power config is not correct.
I know there are drivers for communication with the MCA, but I am not sure how to use them. The mca-cc6ul-core.c file has read register and write register functions, but I have not found a register description for the MCA.
Any help would be appreciated.
