(Ⅰ) Display mode setting commands
These commands initialize the AD6315 and select the number of segments and the number of grids
(1/4- to 1/12- duty, 16 segments to 24 segments).
When these commands are executed, the display is forcibly turned off, and key scanning is also stopped.
To resume display, the display command “ON” must be executed. If the same mode is selected, however,
nothing happens.
