conventions of I
System software should ignore undefined bits D[6:0]. See
“Serial Port Operation" and "Temperature Data Format” for
more details.
TEMP will contain measured temperature data for the selected
zone after the completion of one conversion.
conventions of I
System software should ignore undefined bits D[6:0] during
register reads. Bits [6:0] should be set to zero during register
writes. See "Serial Port Operation" and “Temperature Data
Format” for more details.
