I/O General-purpose input/output
State meaning Asserted: The pin is logic 1.
Deasserted: The pin is logic 0.
Timing Assertion: When output, this
signal occurs on the rising-
edge of the system clock. For
input, it may occur at any time
and input may be asserted
asynchronously to the system
clock.
Deassertion: When output,
this signal occurs on the
rising-edge of the system
clock. For input, it may occur
