Table 16. Unsigned Remote Temperature LSB, Filter Off
(Read Only Address 32h)
13-bit unsigned binary formats with filter off:
BIT D7 D6 D5 D4 D3 D2 D1 D0
Value 0.5 0.25 0.125 0 0 0 0 0
Temperature Data: LSb = 0.125°C filter off or 0.03125°C filter on.
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.
