5.3.3
WRITING A CONFIGURATION BYTE
TO THE DEVICE
When the Master sends an address byte with the R/W
bit low (R/W = 0), the device expects one configuration
byte following the address. Any byte sent after this
second byte will be ignored. The user can change the
operating
mode
of
the
device
by
writing
the
configuration register bits.
If the device receives a write command with a new
configuration setting, the device immediately begins a
new conversion and updates the conversion data.
