Memory management and animation controlling
The "Example for animation" on page 71 shows a possible application of the SDA
9410. 11 still pictures plus one life picture (cup of coffee) are located around a second
life (boat) picture (see picture number 1). The still pictures plus one life picture (cup of
coffee) are located in the slave memory and the life picture (boat) in the master memory.
The user wants to switch now between the cup of coffee and the boat channel. A
possible animation could look like this. The boat will be compressed and disappears
(number 2 and number 3). Due to the fact, that only background colour should be visible,
the parts of the life picture, which disappear after compression, will be overwritten with
the back ground colour. Afterwards the new channel is expanded and overwrites the
border colour (cup of coffee, number 4 and number 5).
To support this and other features several I²C Bus parameters exists, which will be
described in more detail afterwards.
