4.9 SRAM retention in low power modes

The SRAM is retained down to VLLS3 mode.
In VLLS2 the region of SRAM_U from 0x2000_0000 is powered.
In VLLS1 and VLLS0 no SRAM is retained.

4.10 System Register file

This device includes a 32-byte register file that is powered in all power modes. Also, it
retains contents during low-voltage detect (LVD) events and is only reset a power-on
reset.
