RME
One complete frame of length less than or equal to the defined block size (EXMR.RFBS)
or the last part of a frame of length greater than the defined block size has been received.
The contents are available in the RFIFO. The message length and additional information
may be obtained from RBCH and RBCL and the RSTA register.
RPF
A data block of a frame longer than the defined block size (EXMR.RFBS) has been
received and is available in the RFIFO. The frame is not yet complete.
RFO
The received data of a frame could not be stored, because the RFIFO is occupied. The
whole message is lost.
This interrupt can be used for statistical purposes and indicates that the microcontroller
does not respond quickly enough to an RPF or RME interrupt (ISTAH).
XPR
A data block of up to the defined block size (EXMR.XFBS) can be written to the XFIFO.
An XPR interrupt will be generated in the following cases:
• after an XTF or XME command as soon as the 16 or 32 respectively bytes in the
• after an XTF together with an XME command is issued, when the whole frame has
XMR
The transmission of the last frame has to be repeated because a collision has been
detected after the 16
XDU
The current transmission of a frame is aborted by transmitting seven ’1’s because the
XFIFO holds no further data. This interrupt occurs whenever the microcontroller has
failed to respond to an XPR interrupt (ISTAH register) quickly enough, after having
initiated a transmission and the message to be transmitted is not yet complete.
