ADCx_DPx和ADCx_DMx组成了差分输入,除了这些名称的引脚就只有单端功能。
差分输入DPx和DMx也可以作为单端输入用,在参考手册“3.7.1.3 ADC0 connections/channel assignment”就有描述到:As indicated by the following sections, each ADCx_DPx input and certain ADCx_DMx inputs may operate as single-ended ADC channels in single-ended mode.
至于单端时被分配到了哪个channel,你可以通过“Table 3-35. ADC0 channel assignment”表格查看。
