Access:
• WPSWSx: Write Protect SW Status
0 = The Write Protect SW x of the register group x is disabled.
1 = The Write Protect SW x of the register group x is enabled.
• WPHWSx: Write Protect HW Status
0 = The Write Protect HW x of the register group x is disabled.
1 = The Write Protect HW x of the register group x is enabled.
• WPVS: Write Protect Violation Status
0 = No Write Protect violation has occurred since the last read of the PWM_WPSR register.
1 = At least one Write Protect violation has occurred since the last read of the PWM_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) in which a write access has
been attempted.

The two LSBs of the address offset of the write-protected register are not reported
Reading PWM_WPSR automatically clears WPVS and WPVSRC fields.
