In single sweep mode, the input voltages to two, four, six, or eight pins selected from among AN0 to AN11 are A/D
converted once.
Table 23.9 lists the Single Sweep Mode Specifications. Figure 23.9 shows an Operation Example in Single Sweep
Mode.
1. When executing single-sweep mode, set bits CH2 to CH0 in the ADINSEL register to 000b.
