19.3.1.6.2 Software Restore

Even though exiting from the Deep Sleep mode looks like a POR to the device, it is possible to save the connected state of the device in FlexRAM (SRAM) memory. A mechanism, called “software restore”, allows software to indicate when the re-configuration of the device has finished, and it is safe to release the state of this logic and/or I/Os. This is done by clearing the DSCON.DSSR bit.
