I3C Controller is subset of the I3C-basic specification to interface peripherals
|
||
|
|
such as ADCs through I3C.
|
||
|
|
|
||
|
|
It consist out of two sub-modules which communicate over well defined interfaces.
|
||
|
|
The :ref:`i3c_controller core` is a lean but powerful execution module, which
|
||
|
|
implements the I3C bus control logic.
|
||
|
|
It is controlled by a command stream generated by the :ref:`i3c_controller host_interface`,
|
||
|
|
which parses the :ref:`i3c_controller command_descriptors`.
|
||
|
|
|
||
|
|
The :ref:`i3c_controller offload-interface` operation mode allows to execute
|
||
|
|
a pre-programmed command stream when triggered by an external event, allowing for
|
||
|
|
minimal latency.

stream and implements the I3C bus interface logic.
