*
* @brief Configure Device register I2C access
*
* @li 0 : one GLOBAL buffer \n
* Use one global buffer of MAX_I2C_XFER_SIZE byte in data space \n
* This solution is not multi-Device compliant nor multi-thread cpu safe \n
* It can be the best option for small 8/16 bit MCU without stack and limited ram (STM8s, 80C51 ...)
*
* @li 1 : ON_STACK/local \n
* Use local variable (on stack) buffer \n
* This solution is multi-thread with use of i2c resource lock or mutex see VL6180x_GetI2CAccess() \n
*
* @li 2 : User defined \n
* Per Device potentially dynamic allocated. Requires VL6180x_GetI2cBuffer() to be implemented.
