Notes:
1. For a reSTART condition, or following a write cycle.
2. The minimum value delays the falling/rising edge of SDA away from SCL = 1 in order to avoid unwanted START and/or STOP
conditions.

Memory Addressing.
To start communication be-
tween the bus master and the slave M2201, the
master must initiate a START condition. Following
this, the master sends onto the SDA bus line 8 bits
(MSB first) corresponding to the 7th bit byte-ad-
dress and a READ or WRITE bit. This 8th bit is set
to ’1’ for read and ’0’ for write operations. If a match
is found, the corresponding memory will acknow-
ledge the identification on the SDA bus during the
9th bit time.
Write Operations
Following a START condition the master sends the
byte address with the RW bit reset to ’0’. The
memory acknowledges this and waits for a data
byte. Any write command with WC = 1 (during a
period of time from the START condition until the
end of the Byte Address) will not modify data and
will NOT be acknowledged on data bytes, as in
Figure 8.
