https://devzone.nordicsemi.com/f/nordic-q-a/14075/nrf52-s132-v2-0-ram-retentionHey all, What I am trying to achieve today is setting RAM retention on nRF52. As it is stated in Product Specification of nRF52, RAMON register is deprecated ans shouldn&#39;t be used. Ok then, I could use RAM[x].POWER(SET/CLR). But how do i use iten-USTelligent Community 13Thu, 26 May 2016 09:37:23 GMThttps://devzone.nordicsemi.com/thread/53818?ContentTypeID=1Thu, 26 May 2016 09:37:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:10b28769-72cd-4ad2-aa04-bba01b09259dWojtek<p>What i did is solution no.1, setting the registers before enabling SD. It works exactly just as i wanted that way. i thought there may be some problems after enabling sd, but there are not :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/53817?ContentTypeID=1Thu, 26 May 2016 07:55:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:74a72751-f77e-4e00-b717-bf99c65c12c6Susheel Nuguru<p>Hi,</p> <p>Seems like the Softdevice has not yet adapted to this change. There are two options for you.</p> <ol> <li> <p>As you suggested set the RAM blocks before enabling the softdevice if it fits your requirement.</p> </li> <li> <p>If you are designing your code on current hardware versions then you can still use the sd_power_ramon_set API. The RAMON register is still there but could be removed in future chip versions without notice. But it should not matter if your products will be based only on currently available chips.</p> </li> </ol><div style="clear:both;"></div>
