Description
protection_value
This register can be used to ensure that the
software writes a specific value to this register,
before being able to modify any other register in the
device. Three modes of protection are offered,
(i) protected,
(ii) fully unprotected,
(iii) single unprotected.
When protected, no other register in the device can
be written to. When fully unprotected, any writeable
register in the device can be written to. When single
unprotected, only one register can be written before
the device automatically re-protects itself.
Note...This register cannot be protected.
