Note:
Note 1.
Note 2.
The above specification values apply when there is no access to the external bus during A/D conversion. If access proceeds
during A/D conversion, values may not fall within the above ranges.
The conversion time includes the sampling time and the comparison time. As the test conditions, the number of sampling states
is indicated.
The value in parentheses indicates the sampling time.
