1.12 SERIAL INTERFACE RESET
In the event that the SMBus Master is RESET while the
LM95213 is transmitting on the SMBDAT line, the LM95213
must be returned to a known state in the communication pro-
tocol. This may be done in one of two ways:
(c) Serial Bus Read from a Register with the Internal Command Register preset to desired value.
(a) Serial Bus Write to the internal Command Register followed by a the Data Byte
(d) Serial Bus Write followed by a Repeat Start and Immediate Read
(b) Serial Bus Write to the Internal Command Register

When SMBDAT is LOW, the LM95213 SMBus state
machine resets to the SMBus idle state if either SMBDAT
or SMBCLK are held low for more than 35ms (t
Note that according to SMBus specification 2.0 all
devices are to timeout when either the SMBCLK or
SMBDAT lines are held low for 25-35ms. Therefore, to
