the register group is write-protected. The field WPCMD allows to perform the following actions
depending on its value:
At any time, the user can determine which Write Protect is active in which register group by the
fields WPSWS and WPHWS in the
(PWM_WPSR).
If a write access in a write-protected register is detected, then the WPVS flag in the
PWM_WPSR register is set and the field WPVSRC indicates in which register the write access
has been attempted, through its address offset without the two LSBs.
The WPVS and PWM_WPSR fields are automatically reset after reading the PWM_WPSR
register.
• 0 = Disabling the Write Protect SW of the register groups of which the bit WPRG is at 1.
• 1 = Enabling the Write Protect SW of the register groups of which the bit WPRG is at 1.
• 2 = Enabling the Write Protect HW of the register groups of which the bit WPRG is at 1.
