Timer Implementation
Ideally we have to come to a compromise where for space:
- exposing the functionality in C.
- propogating it up to a Python interface.
and for features:
- gettng easy access to the registers so anything can be done.
- exposing useful interfaces for general use.
Finding the right balance is a challenge...
Proposal:
- Expose the registers so a sophisticated user can manipulate all possibilities with care.
- Expose a useful basic interface subset in C and expose as Python class.
Its possible we want to add safety into 1 so that (say) changing a timing mode bit deactivates the clock and bricks the device - is made more difficult.
