CHAPTER 19 8/10-BIT A/D CONVERTER
Operation of Pause-conversion Mode
In the stop conversion mode, the analog input set by the ANS and ANE bits is converted by being
suspended for every channel, the analog input set by the ANE bit is resumed at the end of conversion of the
termination channel set by the ANS bit, and the operation of A/D conversion and suspension is continued.
When the start channel and the termination channel are same (ANS = ANE), the conversion of only
channels specified by the ANS is repeated. When the conversion is restarted during the suspension, the start
factor specified by the STS1 and STS0 bits is generated. For the operation in the stop conversion mode, the
setting as shown in Figure 19.4-3 is necessary.
