Dual 4 bit counter (micro-module)

Simple micro-module comprising a pair or 4 bit counters. Inspired by an element of Matt Keubrich’s Roundabout see here. See also the µr2r for another Roundabout-inspired module…

Controls

None

Connectivity

Inputs and outputs are the same for each counter.

Inputs

Inputs are triggered by positive-going signals.

• c — clock input (increments the 4 bit counter);
• r — reset (sets all outputs to '0')

Outputs

• 4 individual bit outputs.

Each clock input pulse will change the outputs in the following pattern:

0 0 0 0
0 0 0 1
0 0 1 0
0 0 1 1
0 1 0 0
0 1 0 1
0 1 1 0
0 1 1 1
1 0 0 0
1 0 0 1
1 0 1 0
1 0 1 1
1 1 0 0
1 1 0 1
1 1 1 0
1 1 1 1
