17.3.3.2 Possible Error Conditions during Reception of Frames
If parts of a frame get lost because the receive FIFO is full, the Receive Data Overflow
(RDO) bit in the RSTA byte will be set. If a complete frame is lost, i.e. if the FIFO is full
when a new frame is received, the receiver will assert a Receive Frame Overflow (RFO)
interrupt.
The microcontroller sees a cyclic buffer, i.e. if it tries to read more data than available, it
reads the same data block again and again. On the other hand, if it doesn’t read all data,
they are deleted after the RMC command.
If the microcontroller reads data without a prior RME or RPF interrupt, the content of the
RFIFO would not be corrupted, but new data is only transferred to the host as long as
new valid data is available in the RFIFO, otherwise the last data is read again and again.
17.3.3.3 Data Reception Procedure
The general procedures for a data reception sequence are outlined in the flow diagram
in figure 17-18.
