It can be seen from Figure 3 that if the D11 adjacent I/O
cell is used, the I/O group

input is no longer available
as a direct MUX input.
The ispGDXVA can implement MUXes up to 16 bits wide
in a single level of logic, but care must be taken when
combining adjacent I/O cell outputs with direct MUX
inputs. Any particular combination of adjacent I/O cells as
MUX inputs will dictate what I/O groups (A, B, C or D) can
be routed to the remaining inputs. By properly choosing
the adjacent I/O cells, all of the MUX inputs can be
utilized.

Special Features
Slew Rate Control
All output buffers contain a programmable slew rate
control that provides software-selectable slew rate op-
tions.
Open Drain Control
All output buffers provide a programmable Open-Drain
option which allows the user to drive system level reset,
need for an off-chip Open-Drain or Open-Collector buffer.
Wire-OR logic functions can be performed at the printed
circuit board level.
Pull-up Resistor
All pins have a programmable active pull-up. A typical
resistor value for the pull-up ranges from 50k
to 80k
.
Output Latch (Bus Hold)
All pins have a programmable circuit that weakly holds
the previously driven state when all drivers connected to
the pin (including the pin's output driver as well as any
other devices connected to the pin by external bus) are
tristated.
User-Programmable I/Os
The ispGDX240VA features user-programmable
I/Os supporting either 3.3V or 2.5V output voltage level
options. The ispGDX240VA uses a VCCIO pin to provide
the 2.5V reference voltage when used.
PCI Compatible Drive Capability
The ispGDX240VA supports PCI compatible drive capa-
bility for all I/Os.
