Details
This read-only buffer recall attribute is like an array (a Lua table) of the status values for all the readings in the
buffer. The status values are floating-point numbers that encode the status value; see the following table for
values.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
