1.3 SMBus INTERFACE
The LM95214 operates as a slave on the SMBus, so the
SMBCLK line is an input and the SMBDAT line is bidirectional.
The LM95214 never drives the SMBCLK line and it does not
support clock stretching. According to SMBus specifications,
the LM95214 has a 7-bit slave address. Three SMBus device
address can be selected by connecting A0 (pin 6) to either
Low, Mid-Supply or High voltages. The LM95214 has the fol-
lowing SMBus slave address:

1.4 TEMPERATURE CONVERSION SEQUENCE
Each of the 5 temperature channels of LM95214 can be
turned OFF independent from each other via the Channel
Enable Register. Turning off unused channels will increase
the conversion speed in the fastest conversion speed mode.
If the slower conversion speed settings are used, disabling
unused channels will reduce the average power consumption
of LM95214.
1.4.1 Digital Filter
In order to suppress erroneous remote temperature readings
due to noise as well as increase the resolution of the temper-
ature, the LM95214 incorporates a digital filter for Remote 1
and 2 Temperature Channels. When a filter is enabled the
filtered readings are used for the TCRIT comparisons. There
are two possible digital filter settings that are enabled through
the Filter Setting Register at register address 0Fh. The filter
for each channel can be set according to the following table:
R1F[1:0] or R2F[1:0]
