Register Write-Protected Code (Write Only)
Some write-protected registers have to be disabled the protected function by writing the
sequence value “59h”, “16h”, “88h” to this field. After this sequence is completed, the
REGPROTDIS bit will be set to 1 and write-protected registers can be normal write.
Register Write–Protected Disable index (Read only)
1 = Protection is disabled for writing protected registers
0 = Protection is enabled for writing protected registers. Any write to the protected
register is ignored.
The Write-Protected registers list are below table:
