Module configuration
The specific configuration for each ADC instance is listed in the following tables. The module
bus clocks listed here are connected to the system bus clocks according to the table in the Sys-
tem Bus Clock Connections section.
Table 36-13. Module configuration
Table 36-14. Module clock name
Table 36-15. Register Reset Values
The differential inputs of the ADC are configured through the following registers of the ADCIFA:
The configuration allows to select pin or internal voltage.
The ADC voltage reference can be selected as external reference through the RS register of the
ADCIFA.
For detail, see the ADCIFA chapter.
