The third method to reading data from the internal register is to start reading immediately after writing to the
Slave Address and R/W bit. Since the Internal Address Pointer is set to Fh by default as described in the first
method, this method is only effective when reading is started from the Internal Address Fh.
Example 3 of data read (when data is read from internal addresses Fh to 3h)
