24.13.3 Data Length Register (DLR)
68HC908AZ32A — Rev 0.0
MOTOROLA
IDE — ID Extended
RTR — Remote Transmission Request
This register keeps the data length field of the CAN frame.
DLC3–DLC0 — Data Length Code Bits
Freescale Semiconductor, Inc.
This flag indicates whether the extended or standard identifier format
is applied in this buffer. In case of a receive buffer, the flag is set as
being received and indicates to the CPU how to process the buffer
identifier registers. In case of a transmit buffer, the flag indicates to the
MSCAN08 what type of identifier to send.
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 supports 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.
