Data Definition of the single frames
One frame consits of 2 blocks (à 8x9 LED-matrix) or 3 blocks (à 5x6 LED-matrix). This configuration is set in the
AS1119 config register
In the internal DPRAM of the device 6 frames can be stored. For each frame the following parameters have to be
stored.
Note: After power-up the data in the DPRAM is undefined (either ‘0’ or ‘1’).
2 Blocks with 8x9 LED Matrix
The AS1119 can be configured to control two seperated blocks of LEDs matrixes. This must be set via the bit D0 in the
