16.9.16.9 SCCx HDLC RECEIVE BUFFER DESCRIPTOR.The SCCx HDLC controller
uses the receive (RX) buffer descriptor to report information about the data received for each
buffer. An example of the RX buffer descriptor process is illustrated in Figure 16-80.
Note: The communication processor module sets all the status bits in this buffer
descriptor, but you must clear them before submitting the buffer descriptor to the
communication processor module.
