upper half of the input picture (AAFH) and the lower half of the input picture (AASH). If
one of both counter values is greater as 2*TH_MA_AA + 112, the SLAA and ELAA I²C
Bus parameters are set to their default values.
Table 30
It is possible to make the results of the letter box detection visible on screen in real time
to optimize the I²C Bus parameters. The figure below explains the different possibilities.
The I²C Bus parameter VOLBD can be used to switch on (VOLBD=1) or off (VOLBD=0)
the visibility function.
