13.10.21 AIC Write Protect Status Register
Name:
Address:
Access:
Reset:
• WPVS: Write Protect Violation Status
0 = No Write Protect Violation has occurred since the last read of the AIC_WPSR register.
1 = A Write Protect Violation has occurred since the last read of the AIC_WPSR register. If this violation is an unauthorized
attempt to write a protected register, the associated violation is reported into field WPVSRC.
• WPVSRC: Write Protect Violation Source
When WPVS is active, this field indicates the write-protected register (through address offset or code) in which a write
access has been attempted.
