This
function
disables
the
write
‐
protected
register
and
allows
you
to
modify
the
corresponding
register’s
value.
For
example,
to
change
the
gas
conversion
factor,
the
user
needs
to
send
0xAA55
to
the
register
0x0016,
and
then
the
write
function
will
be
enabled
(write
protection
is
disabled).
After
the
write
execution
is
completed,
the
firmware
will
automatically
re
‐
enable
the
write
protection.
