description for SDOFS:(see figure1).Here it is mentioned that the period of
SDOFS pulses would be 1/fsample, just like Figure 10a. My question is for
Figure 10b and 10c, what’s the period of SDOFS pulses? (see figure2) .
For example, if I want to implement Fsample=64K for every channel, what’s the
period of SDOFS and how do I read the output data from channel 1 to channel 6?
The 1/f is when the sample is valid. The start of data pulses is the marker for
the start of the next channel as the data is shifted out.
As long as all the channels are shifted out before the next 1/f the data is the
same time slice. If IRQ’s are used for sampling, disable IRQ while reading
channel 1 to 6 then enable IRQ for next sample. (see figure3 in attached
