Operation Modes
The transceiver has six different operation modes:
– power off mode
– idle mode
– active mode
– charge mode
– local mode
– test mode
In the power off mode circuits are powered down and only sleep clock is
running.
In the idle mode only the circuits needed for power up are supplied.
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 and test modes are used for alignment and testing.
