TMS320F280049: About "4.2.6 Suggestions for Improving Freedom From Interference"

Wayne Huang

Part Number: TMS320F280049


Dear Champs,

I am asking this for our customer.

In P16 of F28004x safety manual (http://www.ti.com/lit/ug/spruid8b/spruid8b.pdf)

4.2.6 Suggestions for Improving Freedom From Interference

It says, 

3. Power down the analog components cores if they are not used.

Does "power down" means to connect unconnected analog pins like ADC, compactor, to analog ground?

OR does "power down" means to disable the clock to the analog modules?

Or others?

Would you please help make it clearer?

    Hi Wayne,

    This requirement can be satisfied by either clock gating or keeping peripheral in reset so that it does not cause interference.

    i.e.

    1. Hold peripherals clocks disabled if the available peripherals are unused (CLK14-Peripheral Clock Gating (PCLKCR)).
    2. Hold peripherals in reset if the available peripherals are unused (SYS7-Peripheral Soft Reset (SOFTPRES)).

    We will update safety manual in next release.

    Regards,
