AD连续转换怎么检查它是否完成和停止

我使用的是PIC18F26K40，当使用连续转换时，我想知道当只有一个比特用于启动转换、检查它是否完成和停止转换时，多个AD信道可以被服务，并且这似乎同时适用于所有信道。例如，连续转换模式-AdCONT＝1；选择一个通道-ADPCH＝0x02；ADC模块打开- ADON＝1；转换开始- ADGO＝1；它完成了-而（ADGO）；得到结果（ADRESH和LT；8）+ ADRESLED似乎所有这些都必须在您移动到下一个频道。但如果是这样的话，那么连续转换和单转换有什么区别呢？

    I am using a PIC18F26K40
When using continuous conversion, I am wondering how multiple AD channels can be serviced when there is only one bit used for starting a conversion, checking if it is complete and stopping conversion, and that seems to apply to all channels at once. For example,

Continuous conversion mode -  ADCONT = 1;

Select a channel  -                    ADPCH = 0x02;
the ADC module is turned on -  ADON = 1;
The conversion is started -       ADGO = 1;
Is it finished -                          while(ADGO);
get the result -                       (ADRESH << 8) + ADRESL

It seems that all this must be done before you move on to the next channel. But if that is the case, then what is the difference between continuous conversion and single conversion.
