Initial Value
• Bit 7:0 – MSG7:0: Message Data
This register contains the CAN data byte pointed at the page MOb register.
After writing in the page MOb register, this byte is equal to the specified message location of the
pre-defined identifier + index. If auto-incrementation is used, at the end of the data register writ-
ing or reading cycle, the index is auto-incremented.
The range of the counting is 8 with no end of loop (0, 1,..., 7, 0,...).
