[model selector] keyword

Hello all,

I was wondering, in the use of the model selector keyword, can one list
POWER, GND, and NC?
The reason I ask, is that in the case of pins that are usable in various
modes, it often involves grounding, or leaving certain other pins
open(NC).

thanx,

roland

NC |default, CLKI, CLKO attached to a crystal
pc5x03 |if CLKO left open (NC), feed external clock signal into CLKI

[Model Selector] PECLbuf
PECL_diff |default, IN(+), IN(-) function as PECL differential
inputs
PECL_single | IN(+) as single sided PECL, decouple IN(-) to ground.
TTL_single | IN(+) as single sided TTL, IN(-) to ground.
GND
