Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

This field specifies bits A6 through A0 of the slave address.
Receive/Send
The R/S bit specifies if the next operation is a Receive (High) or Send
(Low).
Value Description
0 Send.
1 Receive.
