The primary function of the 5-bit multiplexer, 1-bit latch is to enable system configuration. When the MUX_SELECT signal is logic 1, the multiplexer will select the MUX_IN lines to drive on the MUX_OUT pins. The MUX_SELECT signal is also used to latch the NON_MUXED_OUT signal which outputs data from the non-volatile register.
