:
1. A5 is always “0”.
2. R/W = “1” for Read Operations
3. R/W = “0” for Write Operations
4. Denotes a “don’t care” value (shaded areas)

PTION
The user can simplify the design of the circuitry con-
necting to the Microprocessor Serial Interface by ty-
ing both the SDO and SDI pins together, and reading
data from and/or writing data to this combined signal.
This simplification is possible because only one of
these signals are active at any given time. The inac-
tive signal will be tri-stated.
