The E-Ray module communicates with the external world via three I/O lines each
channel. The RXDAx and RXDBx lines are the receive data input signals, TXDA and
TXDB lines are the transmit output signals, TXENA and TXENB the transmit enable
signals.
Clock control, address decoding, and service request control are managed outside the
E-Ray module kernel.
2.5.4.2
For communication on a FlexRay™ network, individual Message Buffers with up to 254
data byte are configurable. The message storage consists of a single-ported Message
RAM that holds up to 128 Message Buffers. All functions concerning the handling of
messages are implemented in the Message Handler. Those functions are the
acceptance filtering, the transfer of messages between the two FlexRay™ Channel
Protocol Controllers and the Message RAM, maintaining the transmission schedule as
well as providing message status information.
The register set of the E-Ray IP-module can be accessed directly by an external Host
via the module’s Host interface. These registers are used to control/configure/monitor
the FlexRay™ Channel Protocol Controllers, Message Handler, Global Time Unit,
System Universal Control, Frame and Symbol Processing, Network Management,
Service Request Control, and to access the Message RAM via Input / Output Buffer.
The E-Ray IP-module supports the following features:

Data Sheet
Conformance with FlexRay™ protocol specification v2.1
Data rates of up to 10 Mbit/s on each channel
Up to 128 Message Buffers configurable
8 Kbyte of Message RAM for storage of e.g. 128 Message Buffers with max. 48 byte
data field or up to 30 Message Buffers with 254 byte Data Sections
Configuration of Message Buffers with different payload lengths possible
One configurable receive FIFO
Each Message Buffer can be configured as receive buffer, as transmit buffer or as
part of the receive FIFO
Host access to Message Buffers via Input and Output Buffer.
Input Buffer: Holds message to be transferred to the Message RAM
Output Buffer: Holds message read from the Message RAM
Filtering for slot counter, cycle counter, and channel
Maskable module service requests
Network Management supported
Four service request lines
Automatic delayed read access to Output Command Request Register (OBCR) if a
data transfer from Message RAM to Output Shadow Buffer (initiated by a previous
write access to the OBCR) is ongoing.
