Initial Power-Up
On initial power-up, the AS1116 registers are reset to their default values, the display is blanked, and the device goes into shutdown mode. At
this time, all registers should be programmed for normal operation.
Note: The default settings enable only scanning of one digit; the internal decoder is disabled and the Intensity Control Register ( see page
Shutdown Mode
The AS1116 devices feature a shutdown mode, where they consume only 200nA (typ) current. Shutdown mode is entered via a write to the Shut-
down Register (see Table 8 ). For the AS1116, at that point, all segment current sources and digital drivers are switched off, so that all segments
are blanked.
Note: During shutdown mode the Digit-Registers maintain their data.
Shutdown mode can either be used as a means to reduce power consumption or for generating a flashing display (repeatedly entering and leav-
ing shutdown mode). For minimum supply current in shutdown mode, logic input should be at GND or V DD (CMOS logic level).
When entering or leaving shutdown mode, the Feature Register is reset to its default values (all 0s) when Shutdown Register bit D7 (page 12) =
0.
Note: When Shutdown Register bit D7 = 1, the Feature Register is left unchanged when entering or leaving shutdown mode. If the AS1116
is used with an external clock, Shutdown Register bit D7 should be set to 1 when writing to the Shutdown Register.
