EF5XX Data Retention Description, Continued
Automatic
Write Protect
The EF5XX can optionally write-protect itself automatically
while the battery capacity is insufficient for saving data
completely. Automatic write protect is controlled by the
parameter BSS_WPLC. The default value of 1 indicates that
data should be protected by write-protecting automatically.
Comprehensive
Battery Test
The BATTST local program provides a comprehensive battery
test that measures the life of the battery under full load. More
information on the battery test is available in Chapter 4.
