When the write lock switch is disabled, set 2
(enabled) for WRITE_LOCK (index 1034) of the
resource block to enable the write lock function. To
enable the write lock function using the WRITE_
LOCK setting, FEATURE_SEL (index 1018) of
the resource block must be returned to its factory
default. (In the factory default setting, “Hard W
Lock” (bit 4) is “0” (Off) and “Soft W Lock” (bit 3) is
“1” (On).
