Functional Description and Application Information
4.8.2.3
Table 89. Wake-up Source Register (WSR)
Reading the WSR will clear the wake-up status bit(s). Writing will have no effect. The Wake-up Source Register (WSR) has to be
read after a wake-up condition, in order to execute a new STOP mode command. Two base clock cycles (f
required between the WSR read and the MCR write.
