timing diagrams
The timing diagrams can be categorized into two major groups: nonconversion and conversion. The
nonconversion cycles are read and write (configuration). None of these cycles carry a conversion. The
conversion cycles are the four modes shown in Figure 7 through Figure 14.
read cycle (read FIFO or read CFR)
read CFR cycle:
The read command is decoded in the first 4 clocks. SDO outputs the contents of the CFR after the 4th SCLK.
