NOTES:
1. If any unused channels are selected, the resulting ADC conversion will be unknown.
2. The voltage levels supplied from internal reference nodes as specified in the table are used to verify the
operation of the ADC converter both in production test and for user applications.
11.8.2 ADC Data Register
One 8-bit result register is provided. This register is updated each time
an ADC conversion completes.
