(Con’t)
Power PC 403 Mode - RDY Ready Output:
This output pin will function as the “active-high” READY
output.
During a READ or WRITE cycle, the Microprocessor Inter-
face block will toggle this output pin to the logic high level,
ONLY when the Microprocessor Interface is ready to com-
plete or terminate the current READ or WRITE cycle. Once
the Microprocessor has sampled this signal being at the
logic “high” level upon the rising edge of PCLK, then it is
now safe for it to move on and execute the next READ or
WRITE cycle.
If (during a READ or WRITE cycle) the Microprocessor
Interface block is holding this output pin at a logic “l(fā)ow”
level, then the Microprocessor is expected to extend this
READ or WRITE cycle, until it samples this output pin
being at the logic low level.
N
OTE
:
The Microprocessor Interface will update the state
of this output pin upon the rising edge of PCLK.

Microprocessor Interface Address Bus Input
These pins permit the Microprocessor to identify on-chip
registers and Buffer/Memory locations within the
XRT86VL38 device whenever it performs READ and
WRITE operations with the XRT86VL38 device.
N
OTE
:
These pins are internally pulled “Low” with a 50k
Ω
resistor, except ADDR[8:14].

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.
