MUXCTRL - ADC Channel MUX Control registers
See
settings, see
Table 25-8.
• Bit 1:0 - INPUTMODE[1:0]: Channel Input Mode
These bits define the channel mode. This setting is independent of the ADC CONVMODE
(signed/unsigned mode) setting, but differential input mode can only be done in ADC signed
mode. In single ended input mode, the negative input to the ADC will be connected to a fixed
value both for ADC signed and unsigned mode.
Table 25-9.
Table 25-10. Channel Input Modes, CONVMODE=1 (signed mode)
The MUX register defines the input source for the channel.
