Figure 2-18. Group of Seven PIOs
Figure 2-19. DQS Routing
PIO
The PIO contains four blocks: an input register block, output register block, tristate register block and a control logic
block. These blocks contain registers for both single data rate (SDR) and double data rate (DDR) operation along
with the necessary clock and selection logic. Programmable delay lines used to shift incoming clock and data sig-
nals are also included in these blocks.
Input Register Block
The input register block contains delay elements and registers that can be used to condition signals before they are
passed to the device core. Figure 2-20 shows the diagram of the input register block.
Input signals are fed from the sysIO buffer to the input register block (as signal DI). If desired the input signal can
bypass the register and delay elements and be used directly as a combinatorial signal (INDD), a clock (INCK) and
