Figure 9 below, the time of Power Down mode is set by register RTINT and register
RTDLY should be set at greater than or equal to ‘0x11’ in order to stabilize the crystal.
In the case of PM1 and PM2,the minimum time until the system is operating after going
into the Power Down mode, is around 534μsec (RTINT:0x01, RTDLY:0x11).
