17.12.3 Data Length Register (DLR)
Technical Data
328
RTR — Remote transmission request
This register keeps the data length field of the CAN frame.
DLC3 – DLC0 — Data length code bits
This flag reflects the status of the Remote Transmission Request bit
in the CAN frame. In the case of a receive buffer it indicates the status
of the received frame and supports the transmission of an answering
frame in software. In the case of a transmit buffer this flag defines the
setting of the RTR bit to be sent.
The data length code contains the number of bytes (data byte count)
of the respective message. At the transmission of a remote frame, the
data length code is transmitted as programmed while the number of
transmitted data bytes is always 0. The data byte count ranges from
0 to 8 for a data frame.
bits.
0 = Data frame
1 = Remote frame
