RLC-6 MODE DESCRIPTION:
The logic for mode selection is "negative true", or active low logic. This means that when selecting the three
control bits, control lines 1,2,3 are read as low=true, high=false.

TERMS:
H - High Voltage (5V) or an open pin
L - Low Voltage (0V) or a grounded pin
The RLC-6 internally pulls up the 3 logical control lines with a 10K resistor. Therefore it is not required that the user
connect any unused lines to +5 V. In order to take a control line low, the user must apply a ground, a logical "LOW",
to the appropriate pin.
