interrupt indications concerned with the reception of data:
• RPF (Receive Pool Full) interrupt, indicating that a 32-byte block of data can be read
• RME (Receive Message End) interrupt, indicating that the reception of one message
The following figure gives an example of a reception sequence, assuming that a “long”
frame (66 bytes) followed by two short frames (6 bytes each) are received.
