Product specification
Stand-alone CAN controller
SJA1000
The lower the binary value of the identifier the higher the
priority. This is due to the larger number of leading
dominant bits during arbitration.
6.4.13.5
Data field
The number of transferred data bytes is defined by the
data length code. The first bit transmitted is the most
significant bit of data byte 1 at CAN address 19 (SFF) or
CAN address 21 (EFF).

R
ECEIVE BUFFER
The global layout of the receive buffer is very similar to the
transmit buffer described in the previous section.
The receive buffer is the accessible part of the RXFIFO
and is located in the range between CAN address
16 and 28. Each message is subdivided into a descriptor
and a data field.
Fig.8 Example of the message storage within the RXFIFO.

6.4.14.1
Descriptor field of the receive buffer
The bit layout of the receive buffer is represented in Tables 34 to 36 for SFF and Tables 37 to 41 for EFF. The given
configuration is chosen to be compatible with the transmit buffer layout (see Section 6.4.13.2).
