Start process
The analog input shares pins P0_1 to P0_4, P0_6, P0_7, and P1_0 to P1_3 in AN0 to AN1, AN3 to AN6, and
AN8 to AN11.
When using the ANi (i = 0, 1, 3 to 6, 8 to 11) 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 28.2 shows a Timing Diagram of A/D Conversion. Figure 28.3 shows the A/D Conversion Cycles ( φ AD
= fAD).
