A927ZET Data Logging area description
A data record is composed by a time-stamp and/or sensor value. Both are not required so one record can also be either
one of these alone. Data record composition is defined by Control register.
Time-stamped Data is a 32 bit data expressed in Unix time-stamp format. It is the calculated real time of logged data
record.
Sensors data value type is defined in the Sensor Characteristic section of the User memory:
