Multiple displays can be cascaded using the CLKSEL
and CLK I/O pins (Figure 16). The display designated as
the MasterClock 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 dis-
play CLK I/O can drive 15 slave CLK I/Os. Use RST to
synchronize all display counters.
