7.5.1.1.3 DC Data Write

The DC data is 168 bits in length, located from bit 167 to bit 0. The TLC6C5724-Q1 device can adjust the output current of each channel using the DC function. The DC function has two adjustment ranges with 7-bit resolution. Table 15 shows the DC data assignments in the DC registers. The high adjustment range DC can adjust output current from 33.3% to 100% of I(OUT)max. The low adjustment range DC can adjust output current from 0% to 66.7% of I(OUT)max. The range control is in bits 194–192 in the function control data latch select the high or low adjustment. Bit 194 controls the OUTB DC range. Bit 193 controls the OUTG DC range, Bit 192 controls the OUTR DC range. For details, see Table 12
