Conversion time
Start process
(Minimum)
The analog input shares pins P0_0 to P0_7, P1_0 to P1_3, and P13_0 to P13_7 in AN0 to AN19.
To use the ANi (i = 0 to 19) pin as input, set the corresponding port direction bit to 0 (input mode).
After changing the A/D operating mode, select an analog input pin again.
Figure 29.2 shows the Timing Diagram of A/D Conversion. Figure 29.3 shows the A/D Conversion Cycles
( AD = fAD).
