Basic Schematics 101:

~ ~ ~

Rule 37: NEVER apply more than one Signal Name to the same Signal. PERIOD.

Rule 38: NEVER apply the same Signal Name to more than one Signal. PERIOD.

~ ~ ~

Rule 274: No "ifs", "ands", or "buts" about any of the preceding 273 Rules.
PERIOD.

Rule 275: Never think that these Rules do not apply to you. PERIOD.

Rule 276: Never forget these Rules. PERIOD.

PERIOD

The other 271 Rules - Don't even ask - If you have been in the industry for
several years now and still don't know them by now, you are in deep yogurt
and nothing will help you - If you are new to the industry, you will learn
them in due time - Patience.
