Table 3-77 describes the return parameters.
| Parameter Bytes | Description |
|---|---|
| Byte 1 | See Table 3-78 |
| Byte 2 | LABB strength setting |
| Byte 3 | LABB gain value |
| MSB | Byte 1 | LSB | |||||
|---|---|---|---|---|---|---|---|
| b7 | b6 | b5 | b4 | b3 | b2 | b1 | b0 |
| b(7:4) | Sharpness strength |
| b(3:2) | Reserved |
| b(1:0) | LABB control:

Table 3-79 shows the bit order and weighting for the LABB gain value, which ranges from 1 to 8 (the controller software limits the lower value to 1).
| b7 | b6 | b5 | b4 | b3 | b2 | b1 | b0 |
|---|---|---|---|---|---|---|---|
| 22 | 21 | 20 | 2–1 | 2–2 | 2–3 | 2–4 | 2–5 |
The software equation to calculate LABB Gain as a fixed point value is shown below:
LABB_gain = add_8lsb(APL) / pre_LABB_APL (//add 8 LSBs (u8.0 / u8.0 = u8.8 / u8.0 = u8.8)
