Figure 102 (I2C block addressing) of SLG468246 datasheet states A[10:8] = "00X" addresses "2 Kbits Register Data Configuration". Since the register address space has 8 bits only, I wonder what A[10:8] = "001" is used for (I2C ping shows the device actually acknowledges at this address).
Is this just reserved for future addressing of larger address spaces (totally 4 Kbits) and has not function behind it? Or does it have a specific function? If yes, which one? Any pitfall?
Thanks for your inputs in advance & best regards
