The Conversion Rate Register controls how often the temperature measurement channels are updated
and compared against the limits. This register is fully accessible at either address.
Bits 3-0 - CONV[3:0] - Determines the conversion rate as shown in
The actual conversion rate for Continuous conversions will depend on the number of diode channels
enabled and is shown in
