Register 15: ADC Sample Sequence Input Multiplexer Select 0 (ADCSSMUX0),
offset 0x040
This register, along with the ADCSSEMUX0 register, defines the analog input configuration for each
sample in a sequence executed with Sample Sequencer 0. If the corresponding EMUXn bit in the
ADCSSEMUX0 register is set, the MUXn field in this register selects from AIN[19:16]. When the
corresponding EMUXn bit is clear, the MUXn field selects from AIN[15:0]. This register is 32 bits
wide and contains information for eight possible samples.
Note: Channels AIN[31:20] do not exist on this microcontroller. Configuring MUXn to be 0xC-0xF
when the corresponding EMUXn bit is set results in undefined behavior.

8th Sample Input Select
The MUX7 field is used during the eighth sample of a sequence executed
with the sample sequencer. It specifies which of the analog inputs is
sampled for the analog-to-digital conversion. The value set here indicates
the corresponding pin, for example, a value of 0x1 when EMUX7 is clear
indicates the input is AIN1. A value of 0x1 when EMUX7 is set indicates
the input is AIN17.
If differential sampling is enabled (the D7 bit in the ADCSSCTL0 register
is set), this field must be set to the pair number "i", where the paired
inputs are "2i and 2i+1".

7th Sample Input Select
The MUX6 field is used during the seventh sample of a sequence
executed with the sample sequencer. It specifies which of the analog
inputs is sampled for the analog-to-digital conversion.

6th Sample Input Select
The MUX5 field is used during the sixth sample of a sequence executed
with the sample sequencer. It specifies which of the analog inputs is
sampled for the analog-to-digital conversion.

5th Sample Input Select
The MUX4 field is used during the fifth sample of a sequence executed
with the sample sequencer. It specifies which of the analog inputs is
sampled for the analog-to-digital conversion.
