 * \brief Microchip Crypto Auth device command object - this is a command builder only, it does
 * not send the command.  The result of a command method is a fully formed packet, ready to send
 * to the ATCAIFace object to dispatch.
 *
 * This command object supports the ATSHA and ATECC device family.
 * The command list is a superset of all device commands for this family.  The command object
 * differentiates the packet contents based on specific device type within the family.

// this is the ATCACommand parameter structure.  The caller to the command method must
// initialize param1, param2 and data if appropriate.  The command method will fill in the rest
// and initialize the packet so it's ready to send via the ATCAIFace.
// this particular structure mimics the ATSHA and ATECC family device's command structures

// Note: pack @ 2 is required, @ 1 causes word alignment crash (though it should not), a known bug in GCC.
// @2, the wire still has the intended byte alignment with arm-eabi.  this is likely the least portable part of atca
