OUTPUT FORMATS
The digital data output from the ADC is available to the user in 8/7/4-bit wide multiplexed formats by
setting control bits MUXOP[1:0]. Latency of valid output data with respect to VSMP is programmable
by writing to control bits DEL[1:0]. The latency for each mode is shown in the Operating Mode Timing
Diagrams section.
Figure 11 shows the output data formats for Modes 1 – 2 and 4 – 6. Figure 12 shows the output data
formats for Mode 3. Table 1 summarises the output data obtained for each format.

FLAGS
The following flags are output during multiplexed modes:
CC can be used in colour modes 1 and 5 to identify the green channel output, from which the blue
and red data can be identified.

OVRNG indicates that the current output data was produced by an input signal that exceeded the
input range limit of the device. 1 = out of range, 0 = within range.
