NOTES:
1 _{ANx8–ANx11 and ANx16–ANx19 have alternate functions when used with an external multiplexer.}
2 _{After calibration, the 50% reference point will read approximately 20 mV below 50%(VRH - VRL). The 50%}
reference point should not be used to calibrate the EQADC. Use the 25% and 75% reference points to
calibrate the EQADC.
3 _{This function is when using an external multiplexer.}
4 _{Refer to the PMC chapter.}
