Revision 2.3
When the device enters low power mode, an additional sleep time is inserted after each
burst, instead of once after every complete burst cycle. As a result, if only one burst is
required, the sleep duration during low power mode is doubled. And if two bursts are
required, the sleep duration is tripled.
