Note: 1. It also can set cascade mode by software. User must set the Master in master mode and Slaves in slave
mode with command. The CS pin must be connected to MCU individually for independent read and
write.
2. Values of the ″R″ resistors are selected depending on the power consumption of the LEDs.
3. In the PCB layout all VDD pins should be connected to the power plane.
4. In the PCB layout all VSS pins should be connected to the GND plane.
