Note
9. A maximum of six single-ended ADC Channels can be accomplished only if the AMUX Buses are not being used for other funcitonality (e.g. CapSense). If the
AMUX Buses are being used for other functionality, then the maximum number of single-ended ADC channels is four. Similarly, if the AMUX Buses are being
used for other functionality, then the maximum number of differential ADC channels is two.
