7647H–AVR–03/12
Atmel ATmega16/32/64/M1/C1
• Bit 2 – RTRMSK: Remote Transmission Request Mask
– 0 - comparison true forced
– 1 - bit comparison enabled.
• Bit 1 – Reserved Bit
Writing zero in this bit is recommended.
• Bit 0 – IDEMSK: Identifier Extension Mask
– 0 - comparison true forced
– 1 - bit comparison enabled.
16.11.5 CAN Time Stamp Registers - CANSTML and CANSTMH
• Bits 15:0 - TIMSTM15:0: Time Stamp Count
CAN time stamp counter range 0 to 65,535.
16.11.6 CAN Data Message Register - CANMSG
• 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,...).
