length code
register (TRTDL)
27-mcan
Address:
ID2 – ID0 — Identifier bits
RTR — Remote transmission request
DLC3 – DLC0 — Data length code bits.
Reset:
These bits contain the least significant bits of the transmit buffer
identifier.
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 ignored, forcing the number of bytes to be 0. The
data byte count ranges from 0 to 8 for a data frame.
the effect of setting the DLC bits.
