-/**************************************************************************
- ** The A/D conversion is done every tick, in three steps:
- **
- ** 1) On the tick interrupt, the conversion of channels 0-3 is started, and
- **    the A/D interrupt is enabled.
- **
- ** 2) After the conversion is done, an interrupt
- **    is generated at level 1, which is the same level as the tick interrupt
- **    itself. This interrupt will be pending until the tick interrupt is
- **    finished.
- **    When the A/D interrupt is finally served, it will read the results
- **    from the first conversion and start the conversion of channels 4-7.
- **
- ** 3) When the conversion of channels 4-7 is finished, the interrupt is
- **    triggered again, and the results are read. This time, no new
- **    conversion is started, it will be done in the next tick interrupt.
- **
- ** Thus, each channel will be updated HZ times per second.
