Cautions 1. When rewriting the FR2 to FR0, LV1, and LV0 bits to other than the same data, stop A/D conversion
once (ADCS = 0) beforehand.
2. The above conversion time does not include clock frequency errors. Select conversion time, taking
clock frequency errors into consideration.
3. While in the hardware trigger wait mode, the conversion time includes the time spent waiting for
stabilization after the hardware trigger is detected.
Remark f
CLK: CPU/peripheral hardware clock frequency
