Table 7. Configuration Byte 1 Bit Assignments
Note 1: Upon application of power, the ADC begins converting. The MSB of the Status Byte register indicates a conversion in
progress. The Status Byte has a value of 80h during conversions and a value of 00h between conversions. Therefore, at power-on,
the Status Byte alternates between 00h and 80h.
