PRODUCTION DATA
Global BC data are seven bits long. The global brightness for all outputs is controlled by the data in the control data latch. The data are used to adjust the constant-current values for the 48-channel constant-current outputs. As explained in the Global Brightness Control (BC) Function section, the BC values are used to adjust the output current from 10% to 100% of the maximum value. When the device is powered on, the BC data are random.
The global BC data bit assignment in the control data latch is shown in Table 8-4. See Table 8-10 for a summary of the BC data value versus set current value.
| CONTROL DATA LATCH BIT NUMBER | BIT NAME | DEFAULT VALUE | CONTROLLED CHANNEL |
|---|---|---|---|
| 351-345 | BCR[6:0] | N/A (no default value) | BC bits[6:0] for red color group channels (OUTR0 to OUTR15) |
| 358-352 | BCG[6:0] | BC bits[6:0] for green color group channels (OUTG0 to OUTG15) | |
| 365-359 | BCB[6:0] | BC bits[6:0] for blue color group channels (OUTB0 to OUTB15) |
