... Datasheet - I²C Interface The AS1119 supports the I²C serial bus and data transmission protocol in fast mode at 1MHz. The AS1119 operates as a slave on the I²C bus. The bus must be controlled by a master device that generates the serial clock (SCL), controls the bus access, and generates the START and STOP conditions. Connections to the bus are made via the open-drain I/O pins SCL and SDA. Figure 14. I² ...

... Slave Transmitter Mode. The first byte (the slave address) is received and handled as in the slave receiver mode. However, in this mode the direction bit will indicate that the transfer direction is reversed. Serial data is transmitted on SDA by the AS1119 while the serial clock is input on SCL. START and STOP conditions are recog- nized as the beginning and end of a serial transfer. ...

... Datasheet - 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 ...
