Where can I find explanation of OSHTSYNC bit and SELFCLRTRREM bit in TBCTL2 register.

what does sentence "Allow one sync pulse to propogate" and "Loop back sync pulse to enable self sync operation" mean?

    Hi Mao,

    More details need to be added for this bit and the explanation of the functionality of this bit is not clear.
    I'll raise a documentation update request for this.

    Just our experienceabout OSHTSYNC:
    - It does what the name says. When properly enabled and armed it allows only one sync pulse to pass.
    - One sync pulse is really only one sync pulse, we tried different things to rearm it without success.
    - You need some luck to enable it. Probably some Flags need to cleared before (TBSTS.SYNCI ?).
    - When initialization fails it jams the sync, making it a ZeroShotSync.
    Our Conclusion:
    Without proper documentation it is to unpredictable.

    Does anyone else got it working reliable?


    Edit:

    Most problems have been caused by the debugger. Probably the OSHTSYNC is working as expected.
