12.3.2.3 DMSx/OPSx - Diagnosis Mode Set / Output Pin Set Commands
Protocol
Each Cycle where a serial data or command frame is sent to the Serial Input [SI] of the SPI interface, a data frame
is returned immediately by the Serial Output [SO]. The content of the SO frame is dependent of the previous
command which has been sent to SI and the content of the actual content of SI: The first Byte send by S_SI
controls the content of the second byte actual returned by S_SO. The second Byte send by S_SI controls the first
byte in S_SO of the next frame. (see Figure 37)
