In repeat sweep mode, the input voltages to two, four, six, or eight pins selected from among AN0 to AN11 are A/D
converted repeatedly.
Table 23.10 lists the Repeat Sweep Mode Specifications. Figure 23.10 shows an Operation Example in Repeat
Sweep Mode.
1. When executing repeat-sweep mode, set bits CH2 to CH0 in the ADINSEL register to 000b.
