Figure 18.8
When the SMP bit in the ADCON2 register is set to 1 (with sample and hold function), A/D conversion rate per pin
increases. The sample and hold function is available in all operating modes. Start the A/D conversion after
selecting whether the sample and hold circuit is to be used or not.
Figure 18.8 shows the Timing Diagram of A/D Conversion.
