set_point_index
[0x01]
These registers are used to associate a set point as source for the bar graph on the left and
on the right side of the LCD. If enabled the bar graph is updated corresponding to the
value of the set point defined with the set_point_index.
The bar graph segments can also be set manually by writing the symbol_direct_access
registers at address 99 and 100 (Table 12 on Page 26).
set_point_index:
defines a set point register that is used as source for the bar graph
EN:
if set to ‘1’ the corresponding bar-graph will be updated to visualize
the value of a set point with the defined set_point_index
