The Conversion Rate Register controls how often the VSOURCE and temperature measurement
channels are updated and compared against the limits. This register is fully accessible at either
address.
Bits 2-0 - T_CONV[2:0] - Determines the conversion rate as shown in Table 5.7. This conversion rate
applies to temperature measurement and source voltage measurement.
