TEMP1l can be accessed using a Read_Byte operation. However, the complete remote temperature result in both TEMP1h
and TEMP1l may be obtained by performing a Read_Word operation on TEMP1h. The MIC280 will respond to a Read_Word
with a command byte of 01h (TEMP1h) by returning the value in TEMP1h followed by the value in TEMP1l. This guaran-
tees that the data in both registers is from the same temperature-to-digital conversion cycle. The Read_Word operation is
diagramed in Figure 3. TEMP1h is the only MIC280 register that supports Read_Word.
**TEMP1l will contain measured temperature data after the completion of one conversion.
