TMS320F2800137: ADC

Hello youjun,

If any conversion has previously occurred, then the value of that conversion says in the ADC result register until another conversion has fully completed. If no conversion has been performed since the last device reset or power up, then the result register reads 0 (reset value).

Best regards,

Each SOC has its own dedicated result register. There are no random values. When you read result register ADCRESULTy, you get the result of the most recently completed conversion of SOCy. The only exception is if this read occurs before SOCy has completed its first conversion after a reset; in this case the result register reads 0 (its reset value).

Best regards,
Ibukun
