Positive supply for logic.
Sets Control Register bits to logic low. The Dot Register contents are unaffected by the
Serial Data input for Dot or Control Register data. Data is entered on the rising edge of
the Clock input.

This input must be a logic low to write data to the display. When CE returns to logic high
and CLK is logic low, data is latched to either the LED output drivers or a Control Register.
Selects either an internal or external display oscillator source. (SEL) (logic low = External
