Naming of signals
A hash mark (#) at the end of the signal name indicates a low-active signal.
Example: RESET#
If a signal can switch between two functions and if this is noted in the name of the signal, the low-active function is marked with
a hash mark and shown at the end.
Example: C / D#
If a signal has multiple functions, the individual functions are separated by slashes when they are important for the wiring.
The identification of the individual functions follows the above conventions.
Example: WE2# / OE#
