HOW TO CONTROL THE TLC59711
To set each function mode, BC color, GS output, 6-bit write command, 5-bit FC data, 21-bit BC data for each
color group, and 192-bit GS data for OUTXn, a total number of 224 bits must be written into the device.
Figure 31 shows the 224-bit data packet configuration.
When N units of the TLC59711 are cascaded (as shown in Figure 32), N × 224 bits must be written from the
controller into the first device to control all devices. The number of cascaded devices is not limited as long as the
proper voltage is supplied to the device at VCC. The packets for all devices must be written again whenever the
data in one packet is changed.
