When the SMP bit in the ADCON2 register is set to “1” (with sample and hold function), A/D conversion
rate per pin increases to 28 φ AD cycles for 8-bit resolution or 33 φ AD cycles for 10-bit resolution. 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.
When performing the A/D conversion, charge the comparator capacitor in the microcomputer.
Figure 16.6 shows the Timing Diagram of A/D Conversion.
Figure 16.7 shows the A/D Conversion Cycles.
