Definition
Active low, will enable a processor to read all
registers in the display.
If CLK SEL (pin 3) is low, then expect an exter-
nal clock source into this pin. If CLK SEL is
high, then this pin will be the master or source
into this pin. If CLK SEL is high, then this pin
will be the master or source for all other
devices which have CLK SEL low.
CLOCK SELECT determines the action of pin
2. CLK I/O, see the section on Cascading for
an example.
Reset. Used to synchronize blinking. Will not
clear the display. The reset pulse should be
less than 1 ms
