ADC Module Block Diagram 8.10.1.1 ADC Configurability Some ADC configurations are individually controlled by the SOCs, while others are controlled by each ADC module. Table 8-7 summarizes the basic ADC options and their level of configurability. Table 8-7. ADC Options and Configuration Levels OPTIONS CONFIGURABILITY Clock By the module(1) Resolution By the module(1) Signal mode By the module Reference voltage source Not configurable (external reference only) Trigger source By the SOC(1) Converted channel By the SOC Acquisition window duration By the SOC(1) EOC location By the module Burst mode By the module(1) (1) Writing these values differently to different ADC modules could cause the ADCs to operate asynchronously. For guidance on when the ADCs are operating synchronously or asynchronously, see the Ensuring Synchronous Operation section of the Analog-to-Digital Converter (ADC) chapter in the TMS320F2837xD Dual-Core Microcontrollers Technical Reference Manual .
