Product Specification
R
The four internal control signals are:
EC: Enable Clock
SR: Asynchronous Set/Reset or H function generator
Input 0
DIN: Direct In or H function generator Input 2
H1: H function generator Input 1.
Input/Output Blocks (IOBs)
User-configurable input/output blocks (IOBs) provide the
interface between external package pins and the internal
logic. Each IOB controls one package pin and can be con-
figured for input, output, or bidirectional signals. Figure 6
shows a simplified functional block diagram of the Spar-
tan/XL IOB.
IOB Input Signal Path
The input signal to the IOB can be configured to either go
directly to the routing channels (via I1 and I2 in Figure 6) or
to the input register. The input register can be programmed
as either an edge-triggered flip-flop or a level-sensitive
latch. The functionality of this register is shown in Table 3,
and a simplified block diagram of the register can be seen in
