23.1.20.6 REMOTE Bit
•
•
The MSGLOST bit is enabled when the data frame receive operation or remote frame transmit operation (data
frame is received after the remote frame is transmitted) shown in Table 23.4 is selected. The MSGLOST bit
becomes 1 (overwrite occurred) when the message slot j (j = 0 to 15) is overwritten by a new receive data while
the NEWDATA bit is 1 (receive operation completed).
Set the MSGLOST bit to 0 (overwrite not occurred) after reading it by a program.
The REMACTIVE bit becomes 1 (remote frame) when the message slot j is set for the remote frame transmit or
receive operation, while the STATE_BASICCAN bit in the CiSTR register is 0 (not in BasicCAN mode).
Then, the REMACTIVE bit becomes 0 (data frame) after the remote frame transmit or receive operation is
completed.
In BasicCAN mode, the REMACTIVE bit in the CiMCTL14 or CiMCTL15 register becomes 0 when the data
frame is received, and becomes 1 when the remote frame is received.
The RSPLOCK bit is enabled when the remote frame receive operation shown in Table 23.4 is selected. The
RSPLOCK bit determines the operation after the remote frame is received.
When the RSPLOCK bit is set to 0 (automatic answering to remote frame enabled), a slot automatically
switches to a transmit slot after the remote frame is received and the message set in the message slot is
automatically transmitted as the data frame.
When the RSPLOCK bit is set to 1 (automatic answering to remote frame disabled), the message is not
automatically transmitted after the remote frame is received.
Set the RSPLOCK bit to 0 when any transmit/receive mode other than remote frame receive mode is selected.
The REMOTE bit determines transmit/receive mode shown in Table 23.4. Set the REMOTE bit to 0 to transmit
or receive the data frame. Set it to 1 to transmit or receive the remote frame.
The following occurs when the remote frame is transmitted or received.
Transmitting the remote frame
Receiving the remote frame
A message set in the message slot j is transmitted as the remote frame. After a transmit operation is
completed, the slot automatically switches to a data frame receive message slot.
If the data frame is received before a remote frame transmit operation is completed, the data frame is stored
into the message slot j and the remote frame is not transmitted.
The message slot receives the remote frame. The RSPLOCK bit determines the operation after the remote
frame is received.
