Storage Usage Monitoring
5.9.1 Description
All variable data is stored in a permanent memory on the
device. The data is stored in various segments for different
access and usage purposes.
Because the number of write cycles in the permanent
memory is limited, the number in each segment is
monitored by a counter.
All data segments are protected with a CRC32 checksum.
