SPI Output Data
15.6.1 First SPI output data
Since the SPI output data is sent when the SBC is receiving data, the output data are dependent of the previous
SPI command, if no Read Only command is used. Under some conditions there is no “previous command”.
Table 24 gives the first SPI output data that is sent to the microcontroller when entering SBC Normal Mode,
depending on the mode where the SBC was before receiving the first SPI command.
