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
