34.16.1.9 SMC Write Protection Status Register
Note: When the write protection feature is enabled and a write
attempt into a protected register is performed, the Write Protection Violation Source
(WPVSRC) bit field in the SMC_WPSR register does not report the right violation source.
As a consequence the value in the WPVSRC bit field is incorrect. This issue does not
affect the write protection feature itself which is fully functional.
