Input/Output Block
The Spartan-IIE FPGA IOB, as seen in
inputs and outputs that support a wide variety of I/O signal-
ing standards. These high-speed inputs and outputs are
capable of supporting various state of the art memory and
bus interfaces. The default standard is LVTTL.

more details on the I/O standards and termination applica-
tion examples, see XAPP179, "Using SelectIO Interfaces in
Spartan-II and Spartan-IIE FPGAs."
The three IOB registers function either as edge-triggered
D-type flip-flops or as level-sensitive latches. Each IOB has
a clock signal (CLK) shared by the three registers and inde-
pendent Clock Enable (CE) signals for each register.
In addition to the CLK and CE control signals, the three reg-
isters share a Set/Reset (SR). For each register, this signal
can be independently configured as a synchronous Set, a
synchronous Reset, an asynchronous Preset, or an asyn-
chronous Clear.
A feature not shown in the block diagram, but controlled by
the software, is polarity control. The input and output buffers
and all of the IOB control signals have independent polarity
controls.
