TMS320F28388D: How to control "ADCSOCA0 Selected Circuit" ?

Part Number: TMS320F28388D

Hi Experts,

spruii0c.pdf shows below diagram(Figure 17-5. ePWM and Output X-BARs Sources) in P2060.

However I don't find registers to control ADCSOCA/B0 Selected circuits.

Could you please let me know how to select a source for these signals ?

Best regards,

Hidehiko

  • Hi Hidehiko,

    First you need to configure one or more ePWMs to  generate an SOCA or SOCB pulse via the event-trigger submodule.  At this point, the pulses could be used for internal ADC triggering or for ADCSOCOUT.

    Then you select which SOCx pulses you want to go out of the device via the ADCSOCOUTSEL register.  EPWMxSOCA pulse go to ADCSOCAO only and EPWMxSOCB pulses go to ADCSOCBO only.  You can then directly select ADCSOCAO or ADCSOCBO via the pinmux or you can use these signal in the X-BAR. 

      

  • Hi Devin,

    Thank you for your reply.

    I understand connections of signals.
