The second method to reading data from the internal register is to start reading immediately after writing to the
Internal Address Pointer and the Transmission Format Register. Although this method is not based on I

C-Bus
standard in a strict sense it still effective to shorten read time to ease load to the master. Set 4h to the transmission
format register when this method used.

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.
