¿ The association between the numerical value and the function has to be done in a sequential
way, considering the function listed on the operative manual. The first function is obtained by
setting 0, while the last function by setting the maximum value allowed by the range.
À To select OFF, set the minimum numerical value allowed by range.
Á To select OFF, set the maximum numerical value allowed by range.

Event Log Reading

The events history is stored in a circular buffer memory. To rebuild the correct time sequence,
it is necessary to read the position of the most recent event, indicated by the buffer pointer, and
go backward starting from it for a number of positions equal to the one indicated by the event
counter.
If the head of the circular buffer is reached (pos. 1), then it is necessary to move to the last
position (pos. 100, tail) and then go back until the most recent event is reached again. Time
stamp values are returned in compacted format, in three registers containing each a couple of
data. For instance register 2100h holds in the MSB the hours and in LSB minutes. The same
criteria is applied to seconds / day and month / year.
