13.8 Receiving Remote Frames
13.8.1 Remote Frame Reception Procedure
The following describes the procedure for receiving a remote frame.
(1) Initializing the CAN Message Slot Control Register
Initialize the CAN Message Slot Control Register for the message slot in which to receive by
writing H'00 to the register.
(2) Verifying that reception is idle
Read the initialized CAN Message Slot Control Register and inspect the TRSTAT (transmit/
receive status) bit to see that reception has stopped and remains idle. If this bit = 1, it means that
the CAN module is accessing the message slot. Therefore, wait until the bit is cleared to 0.
(3) Setting the ID
Set the ID desired to be received in the message slot.
(4) Setting the extended ID register
Set the extended ID register's corresponding bit to 0 when it is desired to receive a standard
frame or 1 when it is desired to receive an extension frame.
(5) Setting the CAN Message Slot Control Register
➀
When remote frame reception needs to be automatically answered (data frame
transmission)
Set the CAN Message Slot Control Register RR (receive request) and RM (remote) bits to
1 by writing H'60 to the register.
➁
When remote frame reception does not need to be automatically answered
Set the CAN Message Slot Control Register RR (receive request), RM (remote), and RL
(automatic answering enable) bits to 1 by writing H'70 to the register.
Note: When in BasicCAN mode, although slots 14 and 15 can receive a remote frame, they
cannot be set to automatically answer the received remote frame.
