3.4.5.1 Squib SPI commands
The following are the modes that are supported by the squib L9659 using SPI.
●
Configuration mode
●
Deployment mode
●
Diagnostic mode
●
Monitor mode
The table below is a summary of the modes and the functions that are achieved be sending
the particular MOSI command. The following sections will provide a full description of bit
settings for each mode. All commands and responses use D13 to achieve odd parity.
The squib circuits can be reset over when sending the appropriate configuration commands
via SPI.
