Side as Input Clock Pin
(T
buffer delay, the clock routing to the PIO CLK input, the clock→Q of the FF, and the delay through the output
buffer. The delay will be reduced if any of the clock branches are not used. The given timing requires that the
input clock pin be located at one of the four center PICs on any side of the device and that a PIO FF be used.
For clock pins located at any other PIO, see the results reported by ORCA Foundry.
