3. Number of messages specification register (NMES: 1Ehex)
This is a register to set the number of messages to be stored in the message memory.
A maximum of 16 messages can be set, with message numbers 0 to 15.
Writing to NMES is enabled when initialize bit INIT of the CAN control register (CANC:
OEhex) is "1".
At reset, NMES is set to "0000".
The bit configuration and relationship between message number and number of messages
are as follows:
4. CAN bus timing register 0 (BTR0: 1Fhex)
This register sets the baud rate prescaler and synchronization jump width (SJW) used for bus
timing. Writing to the BTR0 bit is enabled, when the INIT bit of the CAN control register
(CANC: 0Ehex) is "1".
The bit configuration is as follows:
