• WPEN: Write Protect Enable
0 = Disables the Write Protect if WPKEY corresponds to 0x444D4143 (“DMAC” in ASCII).
1 = Enables the Write Protect if WPKEY corresponds to 0x444D4143 (“DMAC” in ASCII).
Protects the registers:
WPKEY: Write Protect KEY
Should be written at value 0x50494F (“DMAC” in ASCII). Writing any other value in this field aborts the write operation of
the WPEN bit. Always reads as 0.
