Input clock signal used to sample all expansion interface inputs
and clock all expansion interface outputs. GPIO15 maybe used
as the clock source.
Used in Intel and Motorola* multiplexed modes of operation.
No external circuitry needed.
Expansion-bus address used as an output for data accesses over
the expansion bus. Also, used as an input during reset to
capture device configuration. Based on the desired
configuration, various address signals must be tied low in order
for the device to operate in the desired mode.
The configurations available are shown in
These signals have a weak internal pull-up resistor to Vccp. A
4.7-KΩ pull-down resistor may used to set a “0.”
