Note:

These specification values apply when there is no access to the external memory during A/D conversion. If access occurs during

A/D conversion, values might not fall within the indicated ranges.

The use of PORT0 as digital outputs is not allowed when the 12-Bit A/D converter is used.

The characteristics apply when AVCC0, AVSS0, VREFH0/VREFH, VREFL0, VREFL, and 12-bit A/D converter input voltage are

stable.

Note:

When both unit0 and unit1 are used, do not select the following analog input combinations at the same time except the interleave

function. If selected, values might not fall within the indicated ranges.

● AN100 and AN000 or AN001 or AN002

● AN101 and AN000 or AN001 or AN002 or AN003

● AN102 and AN000 or AN001 or AN002 or AN003 or AN004

Note 1. The conversion time includes the sampling and comparison times. The number of sampling states is indicated for the test

conditions.

Note 2. Values in parentheses indicate the sampling time.
