MFR4200 FlexRay Communication Controller
SPLME — Static Payload Length Mismatch Error
This error appears if the payload length written into a static segment transmit message buffer is not equal
to the static payload length configured within the static payload length register SPLR (see
Section 3.2.3.3.11, “Static Payload Length Register
ignored.
1 – SPLME detected.
0 – No SPLME detected.
NMEFTS — Network Management Error Frame Too Short
This error appears if the payload length value of a received message is not big enough to hold the complete
configured NM vector. However, the received part of the NM vector is used for the NM vector update (see
Section 3.2.3.4.6, “Global Network Management Vector n Register, n = [0:5]
1 – NMEFTS detected.
0 – No NMEFTS detected.
NMENF — Network Management Error Null Frame
This error appears if a received message with an NM bit set has a null frame bit set. In that case, the
GNMVnR registers are not updated.
1 – NMENF detected.
0 – No NMENF detected.
ILLADR — Illegal Address
This error appears if the host tries to perform a byte access (a write access, if the HCS12 interface is
selected) or an unaligned word access.
If the HCS12 interface is selected (see chapter
appears, the CC presents the data value 0x0000 to the host and indicates an IILADR error.
1 – ILLADR detected.
0 – No ILLADR detected.

The address space from 0x0400 to 0x1FFF in the MFR4200 memory map
is reserved. Reading this address space results in data 0x0000, while writing
does not change the memory. Reading or writing this address space will set
the ILLADR bit.
