ADC Module Block Diagram 7.10.1.1 ADC Configurability Some ADC configurations are individually controlled by the SOCs, while others are controlled by each ADC module. Table 7-7 summarizes the basic ADC options and their level of configurability. Table 7-7. ADC Options and Configuration Levels OPTIONS CONFIGURABILITY Clock By the module(1) Resolution Not configurable (12-bit resolution only) Signal mode Not configurable (single-ended signal mode only) 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 TMS320F2807x Microcontrollers Technical Reference Manual. www.ti.com TMS320F28076, TMS320F28075 SPRS902J – OCTOBER 2014 – REVISED FEBRUARY 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 83 Product Folder Links: TMS320F28076 TMS320F28075 |
