4.7 External ADC Interface

The external ADC interface operation is configured, controlled, and monitored by the External SoC

Configuration Register (EXTSOCCFG) at address 0x702E. Figure 4-8 illustrates how the Start-of-

Conversion signals for external ADCs are generated by the on-chip PWM modules.
