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

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

• 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.
