Normal mode of operation
1
Device is put in power-down (low-current) mode.
(1) The register contents default to the appropriate setting for normal operation up on RESET.
(2) The patterns given are applicable to the straight offset binary output format. If two's complement output format is selected, the test mode
outputs will be the binary two's complement equivalent of these patterns as described in the Output Information section.
(3) While each bit toggles between 1 and 0 in this mode, there is no assured phase relationship between the data bits D0 through D10. For
example, when D0 is a 1, D1 in not assured to be a 0, and vice versa.
