9.1.3
The ADRES register, shown in Register 9-2, contains
the 8-bit result of the conversion. At the completion of
the ADC conversion:
• 8-bit result is loaded into ADRES.
• GO/DONE bit (ADOCN0<2>) is cleared.
• ADC interrupt flag bit ADIF (INTCON<6> and
• If the ADC interrupt is enabled, an interrupt is also
