Note
8. A maximum of eight 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 functions, then the maximum number of single-ended ADC channels is six. Similarly, if the AMUX Buses are being
used for other functionality, then the maximum number of differential ADC channels is three.
