8.3 Initialization Set Up

After power-up, the internal registers must be initialized to their default values through a hardware reset by applying a low pulse on the RESET pin, as shown in Figure 8-4.

  1. Apply 1.2 V DVDD digital power supply
  2. Apply remaining 1.2 V power supplies (AVDD12, CLKVDD), in no specific order
  3. Apply 1.8 V AVDD18 power supply
  4. Apply hardware reset. After hardware reset is released, the default registers are loaded from internal fuses.
  5. Begin programming the internal registers using the SPI interface.
