23 / 67 page  Page 22 ams Datasheet Document Feedback [v2-01] 2016-Oct-12 AS1130 − Detailed Description Initial Power-Up On initial power-up, the AS1130 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. To bring the device into normal operation the following sequence needs to be performed. Start-Up Sequence • Power-up the AS1130 (connect VDD to a source), the devices is in shutdown; • After 5ms the address of the AS1130 is valid and the first I²C command can be send. • Define RAM Configuration; bit mem_conf in the AS1130 Config Register (see Figure 45) •On/Off Frames •Blink & PWM Sets • Dot Correction, if specified • Define Control Register (see Figure 38) • Current Source • Display options • Display picture / play movie • To light up the LEDs set the shdn bit to ‘1’ for normal operation mode (see Figure 48). Shutdown Mode The AS1130 device features two different shutdown modes. A software shutdown via shutdown register (see Shutdown & Open/Short Register (0x09)) and a hardware shutdown via the RSTN pin. The software shutdown disables all LEDs and stops the internal operation of the logic. A shutdown mode via the RSTN pin additionally powers down the power-on-reset (POR) of the device. In this shutdown mode the AS1130 consumes only 100nA (typ.). |
