Write
to the LM95241 will always include the address byte
and the command byte. A write to any register requires one
data byte.
Reading
the LM95241 can take place either of two ways:
1.
If the location latched in the Command Register is cor-
rect (most of the time it is expected that the Command
Register will point to one of the Read Temperature Reg-
isters because that will be the data most frequently read
from the LM95241), then the read can simply consist of
an address byte, followed by retrieving the data byte.
2.
If the Command Register needs to be set, then an
address byte, command byte, repeat start, and another
address byte will accomplish a read.
Write only
Write/Read same address
Write/Read different address
The data byte has the most significant bit first. At the end of
a read, the LM95241 can accept either acknowledge or No
Acknowledge from the Master (No Acknowledge is typically
used as a signal for the slave that the Master has read its
last byte). When retrieving all 11 bits from a previous remote
diode temperature measurement, the master must insure
that all 11 bits are from the same temperature conversion.
This may be achieved by reading the MSB register first. The
LSB will be locked after the MSB is read. The LSB will be
unlocked after being read. If the user reads MSBs consecu-
tively, each time the MSB is read, the LSB associated with
that temperature will be locked in and override the previous
LSB value locked-in.
