2.5 Temperature Ranges
The measured temperature is segmented into several temperature ranges. The bq78350-R1 uses these
as indication, and, for Lifetime Data Logging, the time spent in each range. The temperature ranges set in
data flash should adhere to the following format:
T1 ≤ T2 ≤ T3 ≤ T4
Figure 2-2. Data Flash Temperature Range Format
See the Temperature Ranges data flash subclass for details on the specific data flash variables.
2.6 Basic Configuration Options
There are a variety of options available in the bq78350-R1 and the companion AFE that influence the
startup conditions, system configuration, and the data measurement system.
2.6.1 DA Configuration
This register is used to configure the setup of various measurement features of the bq78350-R1.
