7.5.2 Register Initialization
After power-up, the internal registers must be initialized to the default values. This reset can be accomplished in one of two ways:
- A hardware reset is applied by a low-going pulse on the RESET pin (widths greater than 10 ns), as shown in Figure 3 and Serial Interface Timing Requirements.
- A software reset is applied by using the serial interface and setting the RST bit (register 00h, bit D0) high. This setting initializes the internal registers to default values and then self-resets the RST bit low. In this case, the RESET pin is kept high (inactive).
See the Serial Interface Timing Requirements section and Figure 3 for timing information.
