When the A/D converter is not used, the VCUT bit in the ADiCON1 register (i=0, 1) isolates the resistor
ladder of the A/D converter from the reference voltage input pin (V
shutting off any current flow into the resistor ladder from the V
When using the A/D converter, set the VCUT bit to "1" (V
the ADiCON0 register to "1" (A/D conversion started). Do not set the ADST bit and VCUT bit to "1"
simultaneously, nor set the VCUT bit to "0" (no V
bit does not affect the V
Figure 17.9 shows an example of the analog input pin and external sensor equivalent circuit.
