BIN_ENA_TIME_STORE register (RW)
Register Address Op. Default
BIN_ENA_TIME_STORE 0x12 RW 0x0000
The register is composed by the following fields:
15 … 2 1 0
BIN15_EN … BIN02_EN BIN01_EN BIN00_EN
0 0 0 0 0 Default
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.

BIN_HLIMIT registers (RW – 16 words)
Register Address Op. Default
BIN_HLIMIT_0 0x13 RW 0x08C0
BIN_HLIMIT_1 0x14 RW 0x0000
... ... .. 0x0000
BIN_HLIMIT_15 0x22 RW 0x0000
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
