Notes:
ORCA
The pin-to-pin timing parameters in this table should be used instead of results reported by
Foundry.
The ECLK delays are to all of the PIOs on one side of the device for middle pin input, or two sides of the device for corner pin input. The delay
includes both the input buffer delay and the clock routing to the PIO clock input.
