asserted, only ADSP is recognized .
Byte Write Enable Input, active LOW.
Sampled on the rising edge of CLK. This
signal must be asserted LOW to conduct a
byte write.
ZZ “sleep” Input, active HIGH. When
asserted HIGH places the device in a
non-time-critical “sleep” condition with data
integrity preserved. For normal operation,
this pin has to be LOW or left floating. ZZ pin
has an internal pull-down.
Bidirectional Data I/O lines. As inputs, they
feed into an on-chip data register that is
triggered by the rising edge of CLK. As
outputs, they deliver the data contained in
the memory location specified by the
addresses presented during the previous
clock rise of the read cycle. The direction of
the pins is controlled by OE. When OE is
asserted LOW, the pins behave as outputs.
When HIGH, DQ

automatically tri-stated during the data
portion of a write sequence, during the first
clock when emerging from a deselected
state, and when the device is deselected,
