Description
Upper Byte
contains the command, which is performed after sending 8 bit to S_SI. The action out of
this command is affecting the Lower Byte of S_SO of the actual communication
frame.
Lower Byte
contains the command and data, which is performed at the end of the actual
communication frame. The action out of this command is affection the Upper Byte
of S_SO of next communication frame.

Description
Upper Byte
contains the data according the command and data in the Lower Byte of the previous
communication Frame.
Lower Byte
contains the data according the command in the Upper Byte of the actual communication
frame
Note: Reading a register needs two SPI frames. In the first frame the RD command is sent. In the second frame the output at
SPI signal SO will contain the requested information. A new command can be executed in the second frame.
12.2.3.3 16- and 2x8-bit protocol mixed.
The 16-bit and 2x8-bit protocols are mixed according the used commands (see Chapter 12.3.1). Special care
should be taken, changing from the 16-bit protocol to the 2x8-bit protocol. In this case, it is important to send a
NOP command to S_SI. Otherwise, by sending instead a Command, a collision between the S_SO data in the
following frame and the Lower Byte of the 2x8-bit protocol will happen (see Chapter 12.2.3.2).
