Cascading Multiple Displays using only the SCE574x.
Multiple displays can be cascaded using the CLK SEL and CLK I/O pins (Figure „Cascading Multiple Displays using only the SCE574X“
(page 13)). The display designated as the MasterClock source should have its CLK SEL pin tied high and the slaves should have their
CLK SEL 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 synchro-
nize all display counters.
