Register 27: ADC Sample Sequence Extended Input Multiplexer Select 0
(ADCSSEMUX0), offset 0x058
This register, along with the ADCSSMUX0 register, defines the analog input configuration for each
sample in a sequence executed with Sample Sequencer 0. If a bit in this register is set, the
corresponding MUXn field in the ADCSSMUX0 register selects from AIN[19:16]. When a bit in
this register is clear, the corresponding MUXn field selects from AIN[15:0]. This register is 32 bits
wide and contains information for eight possible samples.
Note that this register is not used when the differential channel designation is used (the Dn bit is set
in the ADCSSCTL0 register) because the ADCSSMUX0 register can select all the available pairs.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
8th Sample Input Select (Upper Bit)
The EMUX7 field is used during the eighth sample of a sequence
executed with the sample sequencer.
Value Description
0 The eighth sample input is selected from AIN[15:0] using the
ADCSSMUX0 register. For example, if the MUX7 field is 0x0,
AIN0 is selected.
1 The eighth sample input is selected from AIN[19:16] using
the ADCSSMUX0 register. For example, if the MUX7 field is 0x0,
AIN16 is selected.

7th Sample Input Select (Upper Bit)
The EMUX6 field is used during the seventh sample of a sequence
executed with the sample sequencer. This bit has the same description
as EMUX7.
