19. Analog Multiplexer (AMUX0)
The analog multiplexer (AMUX0) module connects physical device pins with analog peripherals, like the ADC and
Capacitive Sensing modules.
For the ADC, the AMUX0 module selects the single channel for ADC measurement. See “Analog-to-Digital
Converter (ADC0)” on page 104 for more information on configuring pins for use with the ADC.
For the CS0 module, the AMUX0 module selects all channels that should be measured together using channel
binding or scanned individually using single- or auto-scan modes. See “Capacitive Sense (CS0)” on page 130 for
more information on configuring pins for use with the CS0 module.
