Cascading Multiple Displays
Multiple displays can be cascaded using the CLKSEL and CLK I/O pins as shown below. The display designated as the Master Clock
source should have its CLKSEL pin tied high and the slaves should have their CLKSEL pins tied low. All CLK I/O pins should be tied
together. One display CLK I/O can drive 15 slave CLK I/Os. Use RST to synchronize all display counters.
