Description
First line of active area = 2 * SLAA
Last line of active area = 2 * ELAA
Status of SLAA
1: SLAA is reliable
0: SLAA is not reliable
Status of SLAA
1: ELAA is reliable
0: ELAA is not reliable
Reliability signal:
1: All values of letter box detection are reliable
0: All values of letter box detection are not reliable
Signals new values for letter box detection
1: new values can be read
I²C Bus ^{0: current letter box detection measurement not finalized}
