Bridge 1.1 API - I3C Common Command Codes

CCC (Common Command Codes)

The CCC (Common Command Codes) provides a set of universal commands supported across multiple devices. The Bridge for Supernova has a few CCCs which can be used to interact with the downstream devices. This section details these CCCs. For more information on this topic see I3C Common Command Codes section.

GETPID

  • Command Request:

    {
  "transaction_id": 9,
  "command": "i3c_ccc_send",
  "params": {
    "cccName": "GETPID",
    "address": "08",
    "pushPullClockFrequencyInMHz": "5",
    "openDrainClockFrequencyInKHz": "2500",
    "cccParams": {}
  }
}

  • Responses:

    1. Immediate promise:

    {
  "transaction_id": "9",
  "status": "success",
  "type": "command_response",
  "is_promise": true,
  "data": {
    "command": "i3c_ccc_getpid"
  }
}

    1. Command result:

    {
  "transaction_id": "9",
  "status": "success",
  "type": "command_response",
  "is_promise": false,
  "data": {
    "is_response_to": "i3c_ccc_getpid",
    "status": "success",
    "result": {
      "payload": ["0", "0", "0", "0", "64", "65"],
      "payload_size": 6
    }
  }
}

  • Command Request:

  • Responses:

    1. Immediate promise:

    1. Command result:

DIRECTENEC

  • Command Request:

  • Responses:

    1. Immediate promise:

    1. Command result:

Note: For DIRECTDISEC the response's format is very similar, except that the accepted events are ["DISINT", "DISCR", "DISHJ"]. For BROADCASTENEC and BROADCASTDISEC is also similar but address parameter is not required.

  • Responses:

    1. Immediate promise:

    1. Command result:

ENTDAA

  • Command Request:

  • Responses:

    1. Immediate promise:

Note: When using this command is necessary to previously run i3c_init_bus followed byi3c_reset_bus.

BROADCASTRSTACT

  • Command Request:

  • Responses:

    1. Immediate promise:

    1. Command result:

Note: Similar to DIRECTRSTACT but does not require an address parameter.
