45.12.35 LCD Write Protect Mode Register
Register Name:
Access Type:
• WPEN: Write Protect Enable
0 = Disables the Write Protect if WPKEY corresponds to0x4C4344 ("LCD" in ASCII).
1 = Enables the Write Protect if WPKEY corresponds to0x4C4344 ("LCD" in ASCII).
Protects the registers:
• WPKEY: Write Protect KEY
Should be written at value 0x4C4344 ("LCD" in ASCII). Writing any other value in this field aborts the write operation of the
WPEN bit. Always reads as 0.
