        }


USER_IRQ_4_EV_STATUS
^^^^^^^^^^^^^^^^^^^^

`Address: 0xf0008800 + 0xc = 0xf000880c`

    This register contains the current raw level of the i0 event trigger.  Writes to
    this register have no effect.

        :caption: USER_IRQ_4_EV_STATUS

        {
            "reg": [
                {"name": "i0",  "bits": 1},

USER_IRQ_4_EV_PENDING
^^^^^^^^^^^^^^^^^^^^^

`Address: 0xf0008800 + 0x10 = 0xf0008810`

    When a  i0 event occurs, the corresponding bit will be set in this register.  To
    clear the Event, set the corresponding bit in this register.

        :caption: USER_IRQ_4_EV_PENDING

        {
            "reg": [
                {"name": "i0",  "bits": 1},

USER_IRQ_4_EV_ENABLE
^^^^^^^^^^^^^^^^^^^^

`Address: 0xf0008800 + 0x14 = 0xf0008814`

    This register enables the corresponding i0 events.  Write a ``0`` to this
    register to disable individual events.
