ceivers or a transceiver and a PC (internal data), or a transceiver and a

Operation Modes

There are five different operation modes:
– power off mode
– idle mode
– active mode
– charge mode
– local mode
In the power off mode only the circuits needed for power up are supplied.
In the idle mode circuits are powered down and only sleep clock is run-
ning.
In the active mode all the circuits are supplied with power although some
parts might be in the idle state part of the time.
The charge mode is effective in parallel with all previous modes. The
charge mode itself consists of two different states, i.e. the fast charge and
the maintenance mode.
The local mode is used for alignment and testing.
