Bit 1 - DAVG_DIS - Disables the dynamic averaging feature on all temperature channels.
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

‘0’ (default) - The temperature measurement range is 0°C to +127.875°C and the data format is
binary.
‘1’ -The temperature measurement range is -64°C to +191.875°C and the data format is offset
binary (see
‘0’ (default) - The dynamic averaging feature is enabled. All temperature channels will be converted
with an averaging factor that is based on the conversion rate as shown in
‘1’ - The dynamic averaging feature is disabled. All temperature channels will be converted with a
maximum averaging factor of 1x (equivalent to 11-bit conversion). For higher conversion rates, this
averaging factor will be reduced as shown in
