Hello

    Hi WHong,

    Both the pbistrun and SL_SelfTest_PBIST follow the PBIST sequence defined in TRM. I don't notice difference.

    1. MSTGCR register: Configure MSTGCR for PBIST clock

    2. MSIENA: Enable PBIST controller 

    3. MSTGCR: enable PBIST self-test

    4. Wait for x vclk cycles

    5. program PACT, ALGO, RINFOL/OU

    6. program OVER, ROM

    7. write DLR to enable the PBIST test

    8. Wait for test to be done
