BINX_EN: if the BINX_EN bit (X = 0..15) is set to 1 the timestamps (2 words - Unix time format) of sampled values which
are in the range of bin X are saved into the logging memory. Default condition is 0 for all flags.
Example:
In case both the sample value and the sample time need to be stored in the log area the sequence of
the logged data in the memory is the following:
Address
Data (16 bit)
0x08A
Sample 1: Temperature value
0x08B
Sample 1: Time (low)
(*)
0x08C
Sample 1: Time (high)
(*)
0x08D
Sample 2: Temperature value
….
….
(*)Time is expressed in Unix format and need 2 words for a single sample.

These registers are used to set the upper limit for the corresponding histogram bin. The lower level corresponds to the
upper level of the previous bin. The lower level of the first bin is fixed to the lower limit of the sensor.
The temperature T in °C is expressed in fixed point 8.5 notation T
