Figure 48. 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
Figure 49. Read Frame Controlled via FS (FS is High When BUSY Falls)
If another data frame is attempted by pulling up FS during an active data frame, then the ongoing frame is
aborted and a new frame is started.
