/*!@brief SBS Commands
*
* These are the defines for the registers of the sensor controller. Each
* define contains the following bit fields:
* - Bit 26:24 specify the controller type where the define belongs to. Bit 24
* (0x1000000) represents the Sensor SHT3X-DFLT controller,
* while bit 25 (0x200000) specifies the Sensor SHT3X-ALT controller.
* If both bits are set (0x300000), the register exists in both controller
* types. Bit 20 is used if no controller is connected to
* identify the remaining valid entries (where SBS_NONE is set).
* - Bit 23:16 contains the number of bytes to read. For 8, 16, or 32 bit values
* SensorRegReadValue() is called, while for more than 4 bytes function
* SensorRegReadBlock() will be used (block command).
* - Bit 15:0 of the enum contains the address as used for the SBS commands sent
* via I2C.
* All command sequences beginn with I²C device address to access the sensor
* controller. The device address depends on the type of battery controller:
* - 0x44 in case of SHT3XL, and
* - 0x45 for the SHT3XH.
* The address can be probed via SensorCtrlProbe().
* @see
* Functions SensorRegReadWord() and SensorRegReadBlock() use these enums.
* A list of all registers can be found in document
* <a href="../SBS_Commands.pdf">SBS Commands</a>.
