Source Routing
The following image shows the API frame exchanges that take place at the UART when sending a
source routed transmission.
Supporting the API
Applications that support the API should make provisions to deal with new API frames that may be
introduced in future releases. For example, a section of code on a host microprocessor that
handles received serial API frames (sent out the module's DOUT pin) might look like this:
