    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.
