Temperature resolution register (read/write)
With this register a user can program the temperature sensor resolution from 9-12 bits as
shown below. The power-on default is always 10 bit (0.25 °C/LSB). The selected resolution
is also reflected in bits (4:3) (TRES1:TRES0) of the capability register.
Table 21.
Table 22.
The default value is 01 for TRES register.
SMBus timeout
The STTS2002 supports the SMBus timeout feature which is turned on by default. If the
host holds SCL low for more than t
bus. This feature is supported even when the device is in shutdown mode and when the
device is driving SDA low.
