Data Read Interlock  
When any temperature channel high byte register is read, the corresponding low byte is copied into  
an internal ‘shadow’ register. The user is free to read the low byte at any time and be guaranteed that  
it will correspond to the previously read high byte. Regardless if the low byte is read or not, reading  
from the same high byte register again will automatically refresh this stored low byte data.

As shown in Table 6.2, all temperatures are stored as an 11-bit value with the high byte representing  
the integer value and the low byte representing the fractional value left justified to occupy the MSBits.
