The master then generates a repeated start condition (a repeated start condition has the same timing as the start
condition). After this repeated start condition, the protocol is the same as F/S-mode, except that transmission
speeds up to 3.4 Mbps are allowed. A stop condition ends the HS-mode and switches all the internal settings of
the slave devices to support the F/S-mode. Instead of using a stop condition, repeated start conditions are used
to secure the bus in HS-mode.
Attempting to read data from register addresses not listed in this section results in FFh being read out.
