Remote Frame Handling

If a remote frame has been received, the internal FSM will compare the identifier to all identifiers of

the mailboxes. The comparison of the identifiers depends on the value of the bit global/local acceptance

mask enable (GAME/LAME) stored in the mailbox and the data held in the global/local acceptance

mask (GAM/LAM).

If there is a matching identifier and the RFH bit in this mailbox is set and this mailbox is configured

as transmit, this message object will be marked as “to be sent” (TRS will be set).

If there is a matching identifier and the mailbox is configured as receive, this message will be

handled like a data frame and the corresponding bit in RMP and RFP will be set.

After finding a matching identifier, no further compare will be done.

RFP

If a remote frame is received in a mailbox configured as receive

mailbox, the corresponding bits in RFPn and RMPn are set. The bits

in RFP can be cleared by writing a “1” to the corresponding bit

position in RMP. Writing a “0” has no effect. If a remote frame in the

mailbox is overwritten by a data frame, the corresponding bit in RFP

is cleared. After power-up, all bits are cleared.
