For general information please refer to
RME ... Receive Message End
One complete frame of length less than or equal to the defined block size (EXMB.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 RFIFOB. The message length and additional
information may be obtained from RBCHB and RBCLB and the RSTAB register.
RPF ... Receive Pool Full
A data block of a frame longer than the defined block size (EXMB.RFBS) has been
received and is available in the RFIFOB. The frame is not yet complete.
RFO ... Receive Frame Overflow
The received data of a frame could not be stored, because the RFIFOB 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 (ISTAB).
XPR ... Transmit Pool Ready
A data block of up to the defined block size 32 or 64 (EXMB.XFBS) can be written to the
XFIFOB.
An XPR interrupt will be generated in the following cases:
• after an XTF or XME command as soon as the 32 or 64 bytes in the XFIFOB are
• after an XTF together with an XME command is issued, when the whole frame has
• after a reset of the transmitter (XRES)
