For STM32L4S5, how to access the calibration register and how to calculate what values to store in that register? We're having a problem with the calibration of the real-time clock. It's significantly off-time over a period of several days.
We believe there is a register setting to calibrate it, how can we debug this issue please? What are the steps to calculate the calibration register value and how do we get them into the register?
