that a long frame (68 byte) followed by two short frames (12 byte each) are received. The
FIFO threshold (block size) is set to 32 byte in this example:
• After 32 byte of frame 1 have been received an RPF interrupt is generated to indicate
• The host reads the first data block from RFIFOx and acknowledges the reception by
• The second 32 byte block is indicated by RPF which is read and acknowledged by the
• The reception of the remaining 4 bytes plus RSTAx are indicated by RME (i.e. the
• The host gets the number of bytes (COUNT = 5) from RBCLx/RBCHx and reads out
• The second frame is received and indicated by RME interrupt.
• The host gets the number of bytes (COUNT = 13) from RBCLx/RBCHx and reads out
• The third frame is transferred in the same way.
