CHAPTER 18 8/10-BIT A/D CONVERTER
18.6.1
Conversion using EI
2
OS
The 8/10-bit A/D converter can use EI
2
OS transfer the A/D conversion result to memory.

Conversion Using EI
2
OS
Figure 18.6-3 shows the sample operation flowchart when EI
2
OS is used.
Figure 18.6-3 Sample Operation Flowchart when EI
2
OS is Used.
When EI
2
OS is used, the conversion data protection function prevents any part of the data from being lost
even in continuous conversion. Multiple data items can be safely transferred to memory.
