APEX 20K Programmable Logic Device Family Data Sheet
Table 10 describes the APEX 20K programmable delays and their logic
options in the Quartus II software.
The Quartus II software Compiler can program these delays
automatically to minimize setup time while providing a zero hold time.
Figure 25 shows how fast bidirectional I/Os are implemented in
APEX 20K devices.
The register in the APEX 20K IOE can be programmed to power-up high
or low after configuration is complete. If it is programmed to power-up
low, an asynchronous clear can control the register. If it is programmed to
power-up high, the register cannot be asynchronously cleared or preset.
This feature is useful for cases where the APEX 20K device controls an
active-low input or another device; it prevents inadvertent activation of
the input upon power-up.
