Synchronisation
- Run controllers act independently...
- ...but parents can control order of state transitions
of their children
- Important to know about synchronisation requirements
to design the RC hierarchy
- Likely controller hierarchy includes additional ``synchronisation''
controller to ensure TTC actions happen before/after other actions
- Also: do we need synchronisation/ordering within one crate?
- ...ie can crate controller just use a list of generic
CtrlModules (or does it need to know which is which)?
- Guess CP/JEP: yes, TTC: no, ROD: yes (if no BUSY),
PP: not sure (pipeline bus?)
