Preliminary Data Sheet
The movie mode detection block contains a fall back circuit. This fall back circuit can be enabled by
the I2C bus parameter AMMON. If AMMON is set to zero, the fall back counter is disabled. In all
other cases the fall back counter is enabled. If the fall back counter is enabled, the failures of the
movie mode detector will be counted. So if a certain threshold is reached, the MOVMO will be
forced to camera mode.
