Figure 45. Read Frame Controlled via CS (FS = 1)
If another data frame is attempted (by pulling CS high and then low) during an active data frame, then the
ongoing frame is aborted and a new frame is started.
2. Serial interface using FS:
A data read operation in this mode is shown in
Figure 46
and
Figure 47
. The MSB of the output data is
available at the rising edge of FS. MSB – 1 is shifted out at the first rising edge after the first falling edge of
SCLK after the FS falling edge. Subsequent bits are shifted at the subsequent rising edges of SCLK.
Figure 46. Read Frame Controlled via FS (FS is Low When BUSY Falls)
If FS is high when BUSY falls, the SDO is updated again with the new MSB when BUSY falls. This is shown in
Figure 47
.
