Write Protected Registers
To prevent any single software error that may corrupt DDRSDRC behavior, the registers listed
below can be write-protected by setting the WPEN bit in the DDRSDRC Write Protect Mode
Register (DDRSDRC_WPMR).
If a write access in a write-protected register is detected, then the WPVS flag in the DDRSDRC
Write Protect Status Register (DDRSDRC_WPSR) is set and the field WPVSRC indicates in
which register the write access has been attempted.
The WPVS flag is automatically reset after reading the DDRSDRC Write Protect Status Register
(DDRSDRC_WPSR).
Following is a list of the write protected registers:
