At the moment of the first acknowledge, the master transmitter becomes a master receiver and the slave
transmitter. This acknowledge is still generated by this slave.
The Stop condition is generated by the master.
(* important) The data read from THIS IC should always be completed in whole two words, not one word,
otherwise the IICBUS may cause error.
