    Channel turn on/off delay measurement

    Hi,
    In the chapter of BDRV(27.3.7), I saw that TLE987x can measure the delay between intended external MOS activation and actual turn on .I don't know how to do it , and is there any demo code to implement it?

    Hi Liang Xiao,

    if you look into into the BDRV.CTRL2 register you will find all functionalities to work with this feature.
    You will need decide which time you want to measure (turn-on/off) by setting:
    BDRV.CTRL2->DLY_DIAG_DIRSEL
    Then you need to decide which MOSFET you want so supervise by setting
    BDRV.CTRL2->DLY_DIAG_CHSEL
    If the BDRV.CTRL2->DLY_STS flag is set to you can read back the measured timing in BDRV.CTRL2->DLY_DIAG_TIM
    Then you will need to set BDRV.CTRL2->DLY_DIAG_SCLR to clear the Diag timer valid flag.
