Self Refresh
Self Refresh is used to control the timing of the refresh operation when the memory is in Self Refresh. When bit A1 is set to 0
then the refresh timing is controlled by the embedded Temperature Sensor. In this mode of operation if the temperature is
higher than 100°C then the refresh will happen every 8ms. If the temperature is below 100°C then the refresh will happen every
32 ms. If the A1 is set to 1 then the refresh timing will be independent from the temperature and fixed to 8 ms.
