Note:
After the EADC pins is configured to ADC analog input, corresponding DINOFF
(Px_DINOFF[31:16]) should be set to 1 to disable digital input path.
6.16.5 Functional Description
The EADC controller consists of a 13 channel analog switch, 13 sample modules and a 12-bit
successive approximation analog-to-digital converter. The EADC operation is based on sample
module 0~12, each of them has its configuration to decide which trigger source to start the
conversion, which channel to convert. Sample module 0~12 can be configured to EADC_CH0~12
channel, and different trigger source. It provides user a flexible means to get the over-sampling
results. The sample module 0~3 and sample module 4~12 are shows as follows.
