HS-mode
To enter the 3.4MHz high speed mode of communication, the device must receive the following sequence of conditions
from the master: a Start condition followed by a Master code (00001XXX) and a Master Non-acknowledge. Once
recognized, the device switches to HS-mode communication. Read/write data transfers then proceed as described in the
sequences above. Devices return to the FS-mode after a STOP occurrence on the bus.
Sequence 5: HS-mode data transfer of the Master writing multiple bytes to the Slave
