• Bit 7 - Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bits 6:3 - MUXPOS[3:0]: MUX selection on Positive ADC input
These bits define the MUX selection for the positive ADC input.
Table 25-12 on page 311
Table 25-11. ADC MUXPOS Configuration when INPUTMODE[1:0] = 00 (Internal) is used
Table 25-12. ADC MUXPOS Configuration when INPUTMODE[1:0] = 01 (Single-ended),
For devices with more then 8 inputs into an ADC multiplexer, the MUXPOS3 bit is used to select
ADC channels 8 (ADC8) and above.
• Bits 2 - Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bits 1:0 - MUXNEG[1:0]: MUX selection on Negative ADC input
These bits define the MUX selection for the negative ADC input when differential measurements
are done. For internal or single-ended measurements, these bits are not in use.
