This is one of the single shot commands. Conversion starts on next rising edge of CSTART.
Figure 9. Mode 00 Single Shot/Extended Sampling (FS signal used, FS pin connected to TMS320 DSP)
CS used as FS input
When interfacing with the TMS320 DSP using conversion mode 00, the FSR signal from the DSP may be
connected to the CS input if this is the only device on the serial port. This will save one output pin from the DSP.
Output data is made available on the rising edge of SCLK and input data is latched on the rising edge of SCLK
in this case.
modes using the FIFO: modes 01, 10, 11 timing
Modes 01, 10, and 11 timing are very similar except for how and when the FIFO is read, how the device is
configured, and how channel(s) are selected.
Mode 01 (repeat mode) requires a two-cycle configuration where the first one sets the mode and the second
one selects the channel. Once the FIFO is filled up to the threshold programmed, it has the option to either read
the FIFO or configure for other modes. Therefore, the sequence is either configure: select : triggered
conversions : FIFO read : select : triggered conversions : FIFO read or configure : select : triggered conversions
: configure : .... Each configure clears the FIFO and the action that follows the configure command depends on
the mode setting of the device.
