Note: A command request always consists of 3 bytes. If the command is shorter, then it must be completed with 0s.

The data on MISO depend on the preceding command.

SPI Configuration CPHA=1

In SPI mode, each command except NOP is started as shown in Figure 3.5. After the execution of a command

(busy = 0), the expected data can be read as illustrated in Figure 3.6 or if no data are returned by the command,

the next command can be sent. The status can be read at any time with the NOP command (see Figure 3.7).
