• WPEN: Write Protect Enable
0 = Disables the Write Protect if WPKEY corresponds to 0x535343 (“SSC” in ASCII).
1 = Enables the Write Protect if WPKEY corresponds to 0x535343 (“SSC” in ASCII).
Protects the registers:
• WPKEY: Write Protect KEY
Should be written at value 0x535343 (“SSC” in ASCII). Writing any other value in this field aborts the write operation of the
WPEN bit. Always reads as 0.
