MSP430G2553: ADC10 Interrupt timing

Part Number: MSP430G2553


Tool/software:

Hi team,

My customer would like to ask the following about ADC.

They are implementing the ADC10 DTC function on the MSP430G2553, but there is something they want to confim.

The DTC is set in one block mode (n = 32 samples), and they would like to wait for the completion of writing the AD value to the specified address area before moving on to the next process.

When will the following ISRs run?

(A) when conversion is completed and data is written to the first ADC10MEM

(B) when conversion of all data is completed and writing to the specified address is completed

It is written in the Datasheet that it is confirmed that it is completed if the flag of ADC10IFG is set,

but it seems that it is stopped at the while statement of the ISR below, perhaps because ADC10IFG is not asserted.

Best Regards,

Kenley
