This IP block simulates a binary synchronous (parallel) MOD-16 counter.
Applications are CPU's, PWM signal generators, etc.
It features:
- tri-direction (pause, count up, count down)
- loadable (use data[3:1], eg. for jump instruction)
- synchronous output(at rising edge) with async (ripple) setup of next count)
- easy to control, fast and scalable (each 1 bit counter only depends on previous counter)
