/**
* \defgroup sbcp_instruction_m SBCP instruction module
*
* \brief Module to define SBCP instruction
*
* A SBCP device could have multiple instruction there is some standard one :
* - SBCP_INST_GET_FIRMWARE : send back the device firmware
* - SBCP_INST_GET_REGISTERS : send back a list of \ref sbcp_register_m
* - SBCP_INS_SET_REGISTERS : sets a list of \ref sbcp_register_m
*
*
* Moreover you can define your own instructions using sbcp_add_instruction(). It
* uses an sbcp_instruction_callback , so you can define what function will be called
* when the instuction will be processed.
*
* \warning : during an sbcp_instruction_callback user are intended to sets the
* response packet throught \ref sbcp_packet_m interface.
