1.13 ONE-SHOT CONVERSION
The One-Shot register is used to initiate a round of conver-
sions and comparisons when the device is in standby mode,
2.0 LM95213 Registers
Command register selects which registers will be read from or written to. Data for this register should be transmitted during the
Command Byte of the SMBus write communication.
P0-P7: Command
Register Summary
insure a timeout of all devices on the bus the SMBCLK
or SMBDAT lines must be held low for at least 35ms.
When SMBDAT is HIGH, have the master initiate an
SMBus start. The LM95213 will respond properly to an
SMBus start condition at any point during the
communication. After the start the LM95213 will expect
an SMBus Address address byte.

after which the device returns to standby. This is not a data
register and it is the write operation that causes the one-shot
conversion. The data written to this address is irrelevant and
is not stored. A zero will always be read from this register. All
the channels that are enabled in the Channel Enable Register
will be converted once and the TCRIT1, TCRIT2 and
TCRIT3 pins will reflect the comparison results based on this
round of conversion results of the channels that are not
masked.
