Should be written at value 0x50574D (“PWM” in ASCII). Writing any other value in this field aborts the write operation of the
WPCMD field. Always reads as 0.
Writing a zero to this bit has no effect.
Writing a one to this bit will allow to set the WPCMD command to the register group x.
0: Disable the Write Protect SW of the register groups of which the WPRGx bit is set to 1.
1: Enable the Write Protect SW of the register groups of which the WPRGx bit is set to 1.
2: Enable the Write Protect HW of the register groups of which the WPRGx bit is set to 1.
3: No effect.
Only a hardware reset of the PWM controller can disable the Write Protect HW.
