The following figure gives an example of a DMA driven transmission sequence with a
supposed frame length of 70 bytes, i.e. programmed transmit byte count (XCNT) equal
69 bytes.

DMA Driven Transmission Sequence Example
7.5 Data Reception
Interrupt Mode
Also 2 32 byte FIFO buffers (receive pools) are provided for each channel in receive direction.
There are two different interrupt indications concerned with the reception of data:
– RPF (Receive Pool Full) interrupt, indicating that a 32 byte block of data can be read from
the RFIFO and the received message is not yet complete.
– RME (Receive Message End) interrupt, indicating that the reception of one message is
completed, i.e. either
is stored in the RFIFO.
After an interrupt has been processed, i.e. the received data has been read from the RFIFO,
this must be explicitly acknowledged by the CPU issuing a RMC (Receive Message Complete)
command.
The CPU has to handle the RPF interrupt before additional 32 bytes are received via the serial
interface which would cause a "Receive Data Overflow" condition.
