Figure 8: SPI single-byte write operation
shows the SPI multi-byte (burst) write protocol. The host sends the write command, multiple pairs of write
address/data and finally terminates the transaction. Note that for each write byte the address has to be sent over
separately.

5.5.3 SPI read operation
SPI read operation supports single-byte as well as multi-byte (burst) reading. Figure 9 shows the SPI single-byte read
protocol. The host sends the read command, read address, gets the read data, and then terminates the transaction.
Figure 10: SPI single-byte read operation
shows the SPI multi-byte (burst) read protocol. The host sends the read command, read address, gets multiple byte
read data, and then terminates the transaction.
