Table 19.3 lists the CAN Reception and Transmission Mode Configuration.
When configuring a slot as a reception slot, note the following points.
(1) Before configuring a slot as a reception slot, be sure to set the CiMCTLj register to 00h.
(2) A received message is stored in a slot that matches the condition first according to the result of reception
(3) In normal CAN operation mode, when a CAN module transmits a message of which ID matches, the
When configuring a slot as a transmission slot, note the following points.
(1) Before configuring a slot as a transmission slot, be sure to set the CiMCTLj registers to 00h.
(2) Set the TrmReq bit in the CiMCTLj register to 0 (not transmission slot) before rewriting a transmission slot.
(3) A transmission slot should not be rewritten when the TrmActive bit in the CiMCTLj register is 1

the number of the slot is, the higher priority it has.

If it is rewritten, an undefined data will be transmitted.

Communication environment configuration mode:
configure the communication mode of the slot.
Configured as a reception slot for a data frame.
Configured as a transmission slot for a remote frame.
(At this time the RemActive = 1.)
After completion of transmission, this functions as a reception
slot for a data frame. (At this time the RemActive = 0.)
However, when an ID that matches on the CAN bus is detected
before remote frame transmission, this immediately functions
as a reception slot for a data frame.
Configured as a transmission slot for a data frame.
Configured as a reception slot for a remote frame.
(At this time the RemActive = 1.)
After completion of reception, this functions as a transmission
slot for a data frame. (At this time the RemActive = 0.)
However, transmission does not start as long as RspLock bit
remains 1; thus no automatic response.
Response (transmission) starts when the RspLock bit is set to 0.
