VALUE REGISTERS

For data synchronization purposes, the MSB register should be read first if the user wants to read both MSB and

LSB registers. The LSB will be locked after the MSB is read. The LSB will be unlocked after being read. If the

user reads MSBs consecutively, each time the MSB is read, the LSB associated with that temperature will be

locked in and override the previous LSB value locked-in
