1.0 Functional Description
(Continued)
1.8 SERIAL INTERFACE RESET
In the event that the SMBus Master is RESET while the
LM95241 is transmitting on the SMBDAT line, the LM95241
must be returned to a known state in the communication
protocol. This may be done in one of two ways:
1.
When SMBDAT is LOW, the LM95241 SMBus state
machine resets to the SMBus idle state if either SMB-
DAT or SMBCLK are held low for more than 35ms
(t
TIMEOUT
). 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
insure a timeout of all devices on the bus the SMBCLK
or SMBDAT lines must be held low for at least 35ms.
2.0 LM95241 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.
2.
When SMBDAT is HIGH, have the master initiate an
SMBus start. The LM95241 will respond properly to an
SMBus start condition at any point during the communi-
cation.After the start the LM95241 will expect an SMBus
Address address byte.
1.9 ONE-SHOT CONVERSION
The One-Shot register is used to initiate a single conversion
and comparison cycle when the device is in standby mode,
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.
