Microprocessor Interface Address Bus Input
These pins permit the Microprocessor to identify on-chip regis-
ters and Buffer/Memory locations within the XRT86VL34
device whenever it performs READ and WRITE operations with
the XRT86VL34 device.

:
These pins are internally pulled “Low” with a 50k

resistor, except ADDR [8:13].

Data Bus Enable Input pin.
This active-low input pin permits the user to either enable or tri-
state the Bi-Directional Data Bus pins (D[7:0]), as described
below.
Setting this input pin “l(fā)ow” enables the Bi-directional Data
bus.
Setting this input pin “high” tri-states the Bi-directional Data
Bus.

Address Latch Enable Input Address Strobe
The exact behavior of this pin depends upon the type of Micro-
processor/Microcontroller the XRT86VL34 has been configured
to operate in, as defined by the PTYPE[2:0] pins.
Intel-Asynchronous Mode - ALE
This active-high input pin is used to latch the address (present
at the Microprocessor Interface Address Bus pins (A[14:0]) into
the XRT86VL34 Microprocessor Interface block and to indicate
the start of a READ or WRITE cycle.
Pulling this input pin “high” enables the input bus drivers for the
Address Bus input pins (A[14:0]). The contents of the Address
Bus will be latched into the XRT86VL34 Microprocessor Inter-
face circuitry, upon the falling edge of this input signal.
Motorola-Asynchronous (68K) Mode - AS*
This active-low input pin is used to latch the data residing on
the Address Bus, A[14:0] into the Microprocessor Interface cir-
cuitry of the XRT86VL34 device.
Pulling this input pin “l(fā)ow” enables the input bus drivers for the
Address Bus input pins. The contents of the Address Bus will
be latched into the Microprocessor Interface circuitry, upon the
rising edge of this signal.
Power PC 403 Mode - No Function -Tie to GND:
This input pin has no role nor function and should be tied to
GND.
