18.12.3 Data Length Register (DLR)
MC68HC912DT128A — Rev 4.0
MOTOROLA
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 case of a receive buffer it indicates the status of
the received frame and allows to support the transmission of an
answering frame in software. In 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 transmission of a remote frame, the
data length code is transmitted as programmed while the number of
transmitted bytes is always 0. The data byte count ranges from 0 to 8
for a data frame.
