Hi,
what is the correct sequence for doing a self-test?

 

Alt. A

1. MSC_CTRL[10] = 1 bit to initiate the internal self-test

    2a. Delay for > 16 ms

        and/or

    2b. Poll MSC_CTRL[10] == 0

3. Read DIAG_STAT

 

Alt. B

1. MSC_CTRL[10] = 1 bit to initiate the internal self-test

2. Delay for > 16 ms

3. Check MSC_CTRL[10] == 0

4. Read DIAG_STAT

 

Alt. C

1. MSC_CTRL[10] = 1 bit to initiate the internal self-test

2. Check DIAG_STAT at next Data Ready interrupt

 

Alt. D?

 

How can I positively identify the end of self-test ?
