.SH TEMPERATURE ERRATA
There are a group of obscure internal properties exposed to protect against an hardware defect in certain batches of the B7 die of some DS18x20 chips. See http://www.1wire.org/en-us/pg_18.html or request AN247.pdf from Dallas directly.
Two character manufacturing die lot. "B6" "B7" or "C2"
.I read-write,unsigned integer
32 bit trim value in the EEPROM of the chip. When written, it does not seem to read back. Used for a production problem in the B7
Read allowed for all chips. Only the B7 chips can be written.
Writing non-zero (=1) puts a default trim value in the chip. Only applied to the B7
Reading will be true (non-zero) if trim value is the blanket value. Again, only B7 chips will register true, and since the written trim values cannot be read, this value may have little utility.
value in the valid range? Non-zero if true, which includes all non-B7 chips.
