• WPVS: Write Protection Violation Status
0 = No Write Protect Violation has occurred since the last read of the SPI_WPSR register.
1 = A Write Protect Violation has occurred since the last read of the SPI_WPSR register. If this violation is an unauthorized
attempt to write a protected register, the associated violation is reported into field WPVSRC.
• WPVSRC: Write Protection Violation Source
This Field indicates the APB Offset of the register concerned by the violation (SPI_MR or SPI_CSRx)
