Read FIFO
Figure 68
To read the FIFO, the chip must be selected first. Therefore, the master must set the
NCS line to low. After this, the instruction byte is shifted in on SDI and stored in the
internal instruction register. The data bits of the FIFO are then shifted out on SDO. The
following byte is a status word that contains the number of valid bits in the data packet.
After completing the read operation, the master sets the NCS line to high.
