XMR … Transmit Message Repeat
The transmission of the last message has to be repeated.
XDU/EXE … Transmit Data Underrun/Extended Transmission End
The actual frame has been aborted with IDLE, because the XFIFOB holds no further
data, but the frame is not yet complete!
In extended transparent mode, this bit indicates the transmission-end condition.
Note: It is not possible to send transparent-frames when a XMR or XDU interrupt is
RFO … Receive Frame Overflow
One frame could not be stored due to occupied RFIFOB (i.e. whole frame has been lost).
This interrupt can be used for statistical purposes and indicates, that the CPU does not
respond quickly enough to an incoming RPF, or RME interrupt.
RFS … Receive Frame Start
This is an early receiver interrupt activated after the start of a valid frame has been
detected, i.e. after a valid address check in operation modes providing address
recognition, otherwise after the opening flag (transparent mode 0), delayed by two bytes.
After an RFS interrupt, the contents of
• RHCRB
• RAL1
• RSTAB – bit 3-0
are valid and can be read by the CPU.
This interrupt must be enabled setting the RIE bit in CCR2.
