8.7 Understanding write protection
The software write lock feature can be enabled, only if the hardware write lock feature is disabled.
If the software write lock feature is enabled without disabling the hardware write lock feature, then
the software write lock feature gets disabled automatically. If the hardware write lock feature is
selected with the hardware jumper being enabled, the selection is rejected. See Figure for jumper
location. For more information on write protection, see Table 38.
