TMS570LS3137： About DCC

Please tell me about DCC 1/2.


Does the clock source set for monitoring by DCC have constraints?
For example, "Can not be used as a basic function".

I think there are no restrictions.

    The only constraints are that the clock source has to be one of the ones in the list of source options. At least, this is true from a device point of view. There may be other constraints based on your system use case and your safety concept that would make using some sources less than ideal for use as a base clock but this would be applied at the system level not the device level. We do have an application note describing how to use the DCC to monitor the PLL with the OSC Clock as the count1 setting/source.

    It can be found here and may be a good reference for you: www.ti.com/.../spna211
