Operating temperature
* To apply Min. value of V
ACC
(oscillation start time tSTA).
* The Min. value of VCLK is the Min. voltage required to retain the time counting function; it is however necessary to maintain VTEM till the
oscillation of the oscillator has stabilized (oscillation start time tSTA).
* The temperature compensation stops working below Min. value of VTEM.
