8.5.3 Display-Test Register (0xXF)
The AS1106/AS1107 devices can operate in two modes: normal mode and display test mode. In display test mode all LEDs are switched on at
maximum brightness (duty cycle is 15/16 (AS1106) or 31/32 (AS1107). The devices remain in display-test mode until the Display-Test Register is
set for normal operation.
Note: All settings of the digit- and control-registers are maintained.
