PIP modes
The controller contains two independent acquisition-channels which provide the scaling factors to support the range of
different modes. With the external memory of 2 Mbit it is possible to select between single, double and multi-PIP modes.
Table 2 gives an overview of the different PIP modes.

Notes
1. The given sub/main sizes are visible PIP sizes, a border is drawn around these PIPs and does not influence these
2. The SAB9075H can be set in automatic mode in which the reduction factors are automatically set by the mode select
PIP positions
The positions are graphically depicted in Figs 5 to 17.
