TRUTH TABLES

For inputs, the following notations are used:

   0  : logic low level
   1  : logic high level
   X  : don't care, either 0 or 1
   /  : rising or positive-edge clock input
   \  : falling or negative-edge clock input
   !/ : not a rising edge, either 0, 1 or \
   !\ : not a falling edge, either 0, 1 or /
   .  : 'continued', used in compressing the table

For outputs, the following notations are used:

   0 : logic low level
   1 : logic high level
   Z : high impedance, either 3-state or open-collector not driving output
   - : no change (latched in closed state, or register value not changed)
   ? : undefined (although some manufacturers may define a behaviour)
   . : 'continued', used in compressing the table
