Data transfer on the I
transmitted Byte is the Slave address (7 bits, MSB first)
followed by the Read/Write bit. A “zero” indicates a “write”
and a “one” indicates a “read” sequence. The byte is
followed by an acknowledgement (mandatory) where the
receiver pulls down the SDA line after the last received bit,
to indicate that the information was received correctly. The
receiver releases the SDA line after the 9
the second byte may be transmitted.

Note about “repeated Start” (Sr)
transaction. The SDA line cannot transition while SCL line
is in High level state, except for START / STOP and Sr
conditions. A Sr condition is a equivalent to a START
condition (SDA line transitions from High to Low while
SCL is High level). However, a STOP condition is not
necessary before a Start. When there is no Stop, the Start is
called Sr:
A Sr condition can happen any time during an I
