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.
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.
