The SPI command set is optimized for a high data rate. Each communication is started by
setting pin 27 (NSS) to LOW level. After a start-up time the command byte is
transmitted. See SPI Timing Example at 500 Kbit/s in the SPI Handling from
Related Links. This byte indicates the desired user action such as reading out the
received RF data. The command byte is followed by the bytes needed to form the desired
command.Figure 3-23. SPI Command Structure
The first two response bytes are always the events.system and events.events bytes and
contain the information on the current system and event status of the ATA8210/15. See Event Handling from
Related Links.
