Section 19 Controller Area Network (RCAN-TL1)
DLC[3:0] (Data Length Code): These bits encode the number of data bytes from 0,1, 2, … 8 that
will be transmitted in a data frame. Please note that when a remote frame request is transmitted the
DLC value to be used must be the same as the DLC of the data frame that is requested.
(2)
This area is used as Local Acceptance Filter Mask (LAFM) for receive boxes.
LAFM: When MBC is set to 001, 010, 011(Bin), this field is used as LAFM Field. It allows a
Mailbox to accept more than one identifier. The LAFM is comprised of two 16-bit read/write
areas as follows.
If a bit is set in the LAFM, then the corresponding bit of a received CAN identifier is ignored
when the RCAN-TL1 searches a Mailbox with the matching CAN identifier. If the bit is cleared,
then the corresponding bit of a received CAN identifier must match to the STDID/IDE/EXTID set
in the mailbox to be stored. The structure of the LAFM is same as the message control in a
Mailbox. If this function is not required, it must be filled with ‘0’.
Important: RCAN-TL1 starts to find a matching identifier from Mailbox-31 down to Mailbox-0.
As soon as RCAN-TL1 finds one matching, it stops the search. The message will be stored or not
depending on the NMC and RXPR/RFPR flags. This means that, even using LAFM, a received
message can only be stored into 1 Mailbox.
