| 13 | This controller is present on AW20036/AW20054/AW20072. |
| 14 | It is a 3x12/6x9/6x12 matrix LED programmed via |
| 15 | an I2C interface, up to 36/54/72 LEDs or 12/18/24 RGBs, |
| 16 | 3 pattern controllers for auto breathing or group dimming control. |

| 59 | Note that a driver will take the minimum of all LED limits |
| 60 | since the chip has a single global setting. |
| 61 | The maximum output current of each LED is calculated by the |
| 62 | following formula: |
| 63 | IMAXled = 160000 * (592 / 600.5) * (1 / display-rows) |
| 64 | And the minimum output current formula: |
| 65 | IMINled = 3300 * (592 / 600.5) * (1 / display-rows) |
