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.
