Remark n = 0, 1, …, 7
An A/D conversion operation is started on the analog input pin set by the A/D converter mode register (ADM). As soon
as the A/D conversion operation ends, another A/D conversion operation is performed on the same analog input pin.
An A/D conversion end interrupt request (INTAD) is generated at the end of each A/D conversion operation.
If a valid edge is input to the INTP5 pin during an A/D conversion operation, the A/D conversion operation being
performed at that time is suspended, and a new A/D conversion operation is started.
When conversion operation is started, an A/D conversion operation is started on the ANI0 pin input. When the A/D
conversion operation ends, an A/D conversion operation is started on the next analog input pin. An A/D conversion
end interrupt request (INTAD) is generated at the end of each A/D conversion operation.
If a valid edge is input to the INTP5 pin during an A/D conversion operation, the A/D conversion operation being
performed at that time is suspended, and a new A/D conversion operation is started on the ANI0 pin input.
