7.2
Only the Read Command and the Write Command
have Data Byte(s).
The Write command concatenates the 8-bits of the
Data Byte with the one data bit (D8) contained in the
Command Byte to form 9-bits of data (D8:D0). The
Command Byte format supports up to 9-bits of data so
that the 8-bit resistor network can be set to Full-Scale
(100h or greater). This allows wiper connections to
Terminal A and to Terminal B. The D9 bit is currently
unused.
