Data Sheet
Figure 17-18 Data Reception Procedures
Figure 17-19 gives an example of an interrupt controlled reception sequence, supposed
that a long frame (68 byte) followed by two short frames (12 byte each) is received. The
FIFO threshold (block size) is set to 32 byte in this example:
After 32 bytes of frame 1 have been received an RPF interrupt is generated to indicate
that a data block can be read from the RFIFO.
