Notes:
1.
X = Don’t Care, H = High, L = Low
2.
W = T (True) and F (False) is defined in the Byte Write Truth Table preceding.
3.
G is an asynchronous input. G can be driven high at any time to disable active output drivers. G low can only enable active drivers (shown
as “Q” in the Truth Table above).
4.
All input combinations shown above are tested and supported. Input combinations shown in gray boxes need not be used to accomplish
basic synchronous or synchronous burst operations and may be avoided for simplicity.
5.
Tying ADSP high and ADSC low allows simple non-burst synchronous operations. See
BOLD
items above.
6.
Tying ADSP high and ADV low while using ADSC to load new addresses allows simple burst operations. See
ITALIC
items above.
