39.7.31 PWM Write Protection Status Register
Name: PWM_WPSR
Address: 0x400200E8
Access: Read-only
• 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.
1: At least one Write Protect violation has occurred since the last read of the PWM_WPSR. 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.
Note: The two LSBs of the address offset of the write-protected register are not reported
Note: Reading PWM_WPSR automatically clears WPVS and WPVSRC fields.
