Initial Power-Up
On initial power-up, the AS1119 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
17) and
(see page
21) is set to the minimum values.
Shutdown Mode
The AS1119 device features two different shutdown modes. A software shutdown via shutdown register
(see Shutdown
Register (0x0A) on page 27)
and a hardware shutdown via the RSTN pin.
The software shutdown disables all LED’s and stops the internal operation of the logic. A shutdown mode via the
RSTN pin additionally powers down the power-on-reset (PO) of the device. In this shutdown mode the AS1119 con-
sumes only 100nA (typ.).
