CAN Time Stamp Registers - CANSTML and CANSTMH
CAN Data Message Register - CANMSG
• Bit 2 – RTRMSK: Remote Transmission Request Mask
• Bit 1 – Reserved Bit
Writing zero in this bit is recommended.
• Bit 0 – IDEMSK: Identifier Extension Mask
• Bits 15:0 - TIMSTM15:0: Time Stamp Count
CAN time stamp counter range 0 to 65,535.
• 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
writing or reading cycle, the index is auto-incremented.
The range of the counting is 8 with no end of loop (0, 1,..., 7, 0,...).
