REGISTER
The Configuration Register controls the basic operation of the device. This register is fully accessible
at either address.
Bit 6 - RUN / STOP - Controls Active/Standby modes.
Bit 1 - DAVG_DIS - Disables the dynamic averaging feature on all temperature channels (see
Section
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
Config
R/W
R/W
‘0’ (default) - The device is in Active mode and converting on all channels.
‘1’ -The device is in Standby mode and not converting.
‘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 (i.e.
more conversions per second), this averaging factor will be reduced as shown in
CONV[2:0]
4.2.6).
