TMS320F28377D: ADC result register protection

Part Number: TMS320F28377D

Hi,

In the Datasheet (SPRS880O), "Table 9-5. Peripheral Registers Memory Map", the table implies that ADC result registers are not protected? What does that actually mean?

If CPU reads the results register without checking the busy bits of the ADC, and if ADC has not finished the conversion, will CPU read half baked value (half new/half previous value) or just previous value?

Thank you.

    Hello Gobind,

    The column has a (1) link next to it. If you click on it, it will lead you to the following annotation:

    The CPU can only read new or stale values, there is no half-baked values.
