* priority selection:

- just `enable` captures `data`
- just `reset` sets state to 0
- if `enable` and `reset` are both asserted in the same cycle, refer to the priority configuration to figure out which prevails

behavior of `reset_over_enable = false` as currently described:
- just `enable` captures `data`
- just `reset` does nothing
- only when you assert both does the thing reset
