MUXCTRL - ADC Channel MUX Control registers
Table 20-6.
Table 20-7.
The MUX register defines the input source for the channel.
• Bit 7 - Reserved
This bit is unused and reserved for future use. For compatibility reasons 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.
