For more information on Write Protection Registers, refer to
• WPEN: Write Protect Enable
0 = Disables the Write Protect if WPKEY corresponds to 0x50494F (“PIO” in ASCII).
1 = Enables the Write Protect if WPKEY corresponds to 0x50494F (“PIO” in ASCII).
Protects the registers:
• WPKEY: Write Protect KEY
Should be written at value 0x50494F (“PIO” in ASCII). Writing any other value in this field aborts the write operation of the
WPEN bit. Always reads as 0.
