Application Modes 

The  SC4415  is  a  serial  bus  controller  capable  of  performing  multiple  serial  protocols.  In  order  to  support  multiple 
protocols, the SC4415’s functionality has been broken up into several logical application modes. Table  3.3-1 provides 
details about each of the application modes.

Table 3.3-1 – Application Modes 

Applications  modes  are  either  standard  or  licensed.  Standard  modes  are  available  for  all  devices  whereas  licensed 
modes are available with the purchase of a license key. For more information about license keys and applying them to 
an SC4415 device, refer to Section 5.1.3.  

Each  application  mode  enables  a  unique  command  set.  In  addition  to  the  unique  command  set,  a  set  of  general 
commands are also available in every mode. The general commands provide access to base functionalities of the Scout 
such as command mode selection, trigger configuration, and GPIO  functions. Table  3.3-2 lists the general commands 
available.

Table 3.3-2 – General Commands 

3.3.1

 

Boot Mode 

The Boot mode is the mode of operation that is enabled upon power-up. The Boot mode has limited functionality as it 
is primarily intended as a consistent  starting point. The Boot mode is required as some devices may have a different 
selection of available modes of operation depending on which features have been licensed for a specified device. The 
available commands in this mode are 

Version

, 

Update

, 

License

, and 

Mode

. In most cases the only required action after 

first booting Scout is to select the desired application mode.  

The  example  below  shows  the  user  querying  the  mode  of  operation  after  Scout  has  been  booted.  The  current 
operating mode is listed as 0 which indicates the current mode as BOOT. The next operation shows the selection of the 
desired operating Mode, in this case, it is SPI mode.
