Hello,
"approx. ADREFHI" and "approx.ADREFLO" are appear in "Table 19-4" of TRM.
Why the AD conversion result is "approx"?
In the following thread, "There will be some drop due to the resistive pull down to ADRefLo, hence the "approx. ADRefHi" expected conversion result." is described.
However I can't understand what channel is meant for the suggestion.
Could you teach me why "approx" is used concretely?
Best Regards.
