PRODUCTION DATA
The device provides two different interface modes for reading the conversion result. These modes offer flexible hardware connections and firmware programming. Table 7-8 shows how to select one of the two interface modes.
CFR.B11 | CFR.B10 | INTERFACE MODE | MINIMUM SCLK FALLING EDGES REQUIRED TO VALIDATE WRITE OPERATION N |
---|---|---|---|
0 | 0 | 32-CLK, dual-SDO mode (default) | 32 |
0 | 1 | 32-CLK, single-SDO mode | 48 |
In the 32-CLK interface modes, the device uses an internal clock to convert the sampled analog signal. The conversion is completed during the first 16 periods of SCLK and the conversion result can be read on the subsequent SCLK falling edges.
The following sections detail the various interface modes supported by the device.
