In other words there is no need to set it explicitly when using the radio.&nbsp;</p> <p>Generally you don&#39;t need to use this register at all, since the radio will not draw any power unless you enable it in TX or RX mode.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
