• Manufacturer: Infineon Technologies Corporation

Note: The reset value cannot be read right after reset as all interrupts are masked, i.e.
RME
RPF
RFO
XPR
Data Sheet
the XPR interrupt remains internally stored and can only be read as soon as the
corresponding mask bit is set to “0”.

inactive
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.
inactive
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.
inactive
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 a RPF or
RME interrupt (ISTAH).
