t
d(parallel_out)
Delay between low to high, or high to low transition of general-purpose output signals 6 ns
that can be configured by an application in parallel, e.g. all signals in a GIOA port, or
all N2HET1 signals, etc.
(1) This specification does not account for any output buffer drive strength differences or any external capacitive loading differences. Check
Table 5-4 for output buffer drive strength information on each signal.
