Figure 18-26:
Setting transmission request (TRQ) to transmit message buffer after redefinition
Cautions: 1. When a message is received, reception filtering is performed in accordance with
the ID and mask set to each receive message buffer. If the procedure in <~Refer-
ence>Figure 18-38 on page 843 is not observed, the contents of the message
buffer after it has been redefined may contradict the result of reception (result of
reception filtering). If this happens, check that the ID and IDE received first and
stored in the message buffer following redefinition are those stored after the mes-
sage buffer has been redefined. If no ID and IDE are stored after redefinition,
redefine the message buffer again.
2. When a message is transmitted, the transmission priority is checked in accor-
dance with the ID, IDE, and RTR bits set to each transmit message buffer to which
a transmission request was set. The transmit message buffer having the highest
priority is selected for transmission. If the procedure in <~Reference>Figure 18-
26 on page 808 is not observed, a message with an ID not having the highest pri-
ority may be transmitted after redefinition.
