I/O Block
Each user-configurable I/O block (IOB), shown in
Figure 3, provides an interface between the external
package pin of the device and the internal user logic.
Each IOB includes both registered and direct input
paths and a programmable 3-state output buffer which
may be driven by a registered or direct output signal.
Configuration options allow each IOB an inversion, a
controlled slew rate, and a high-impedance pull-up.
Each input circuit also provides input clamping diodes
to provide electrostatic protection and circuits to inhibit
latch-up produced by input currents.
The input buffer portion of each IOB provides threshold
detection to translate external signals applied to the
package pin to internal logic levels. The global input-
buffer threshold of the IOB can be programmed to be
compatible with either TTL or CMOS levels. The buff-
ered input signal drives the data input of a storage
element which may be configured as a positive-edge
triggered D flip-flop or a low-level transparent latch. The
sense of the clock can be inverted (negative edge/high
transparent) as long as all IOBs on the same clock net
use the same clock sense. Clock/load signals (IOB pins
.ik and .ok) can be selected from either of two die edge
metal lines. I/O storage elements are reset during con-
figuration or by the active-low chip

input. Both
direct input (from IOB pin .i) and registered input (from
IOB pin .q) signals are available for interconnect.
