Note 1:
2:
The A/D conversion result never decreases with an increase in the input voltage.
VREFH current is from the RA3/AN3/VREF+ pin or VDD, whichever is selected as the VREFH source. VREFL current is from
the RA2/AN2/VREF-/CVREF pin or VSS, whichever is selected as the VREFL source.
5. Module: HLVD
Note 1 under Register 26-1: HLVDCON, on
page 387, should direct to Parameter D420:
Note 1: For the electrical specifications, see Parameter D420 in Section 31.0 “Electrical Characteristics”.
6. Module: Power-up Timer Period
Table 31-11 on page 572 of the data sheet,
Parameter 33 TPWRT will be revised to a typical value
of 1.0 ms.
