If MUX_SELECT = 0, the MUX_OUT_X pin output values will equal the previously
stored EEPROM byte 0 values regardless of the last non-volatile EEPROM byte
selected by the command byte prior to power-down.
If MUX_SELECT = 1, the MUX_OUT_X output values will equal the MUX_IN_X pin
input values as shown in
