Table 6. Command Byte Register Map (continued)
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.

Masks out all ALERT interrupts if high.
Standby mode control bit; if high, the device immediately stops converting and
enters standby mode. If low, the device enters normal conversion mode.
High masks out OVERT and ALERT interrupts due to remote-diode 1.
High masks out OVERT and ALERT interrupts due to remote-diode 2.
