Vince,

In regards to my previous post (link above), I did some more checking around and it seems that VCLK is a term that comes from the automotive CAN\LIN terminology.

Could you forward a request to the Technical Publications department to clarify this VCLK nomenclature is a LIN term. And, that in the TI world it is actually 'the SYSCLK (or more precisely, "PERx.SYSCLK")', quoted per your prior response. Thanks.

    HI MonkeyBusiness,

    Thanks for your request! We actually have addressed this for all devices because of that original post. There will now be a bullet in the baud rate area where VCLK is mentioned, describing the VCLK source for these devices (and that frequency is == SYSCLK). Because PERx.SYSCLK for LIN == SYSCLK in all recent devices, this has been clarified accordingly.

    Thanks for your recommendation!

    Regards,

    Vince

    HI MonkeyBusiness,

    NOTE: release schedule for device TRMs varies per device. Next available release for all devices should have this update.

    Regards,
