• 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.
