23.13.3 Data Length Register (DLR)
23.13.4 Data Segment Registers (DSRn)
MC68HC908AZ60A — Rev 2.0
MOTOROLA
This register keeps the data length field of the CAN frame.
DLC3–DLC0 — Data Length Code Bits
The eight data segment registers contain the data to be transmitted or
received. The number of bytes to be transmitted or being received is
determined by the data length code in the corresponding DLR.
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.
