PRODUCTION DATA
For increased flexibility, a combination of serial interface registers and parallel terminal controls (CTRL1 to CTRL3) can also be used to configure the device. To enable this option, keep RESET low. The parallel interface control terminals CTRL1 to CTRL3 are available. After power-up, the device is automatically configured according to the voltage settings on these terminals (see Table 7-8). SEN, SDATA, and SCLK function as serial interface digital terminals and are used to access the internal registers of the ADC. The registers must first be reset to the default values either by applying a pulse on the RESET terminal or by setting the RESET bit to '1'. After reset, the RESET terminal must be kept low. The Serial Register Map section describes register programming and the register reset process in more detail.
