Table 7-3 Analog Channel Status Bits
GO/DONE - A/D Conversion Status bit determines current status of conversion:
● 1 - A/D conversion is in progress; and
● 0 - A/D conversion is complete. This bit is automatically cleared by hardware when the A/D conversion is
completed.
ADON - A/D On bit enables A/D converter.
● 1 - A/D converter is enabled; and
● 0 - A/D converter is disabled.
ADCON1 Register
Fig. 7-5 ADCON1 Register
ADFM - A/D Result Format Select bit
● 1 - Conversion result right justified. Six most significant bits of the ADRESLH are not used; and
● 0 - Conversion result left justified. Six least significant bits of the ADRESL are not used.
VCFG1 - Voltage Reference bit selects negative voltage reference source needed for A/D converter operating.
