AT90CAN32/64/128
• Bits 15:0 - TIMTTC15:0: TTC Timer Count
CAN TTC timer counter range 0 to 65,535.
• Bit 7:0 – TEC7:0: Transmit Error Count
CAN transmit error counter range 0 to 255.
• Bit 7:0 – REC7:0: Receive Error Count
CAN receive error counter range 0 to 255.
• Bit 7:4 – HPMOB3:0: Highest Priority MOb Number
MOb having the highest priority in CANSIT registers.
If CANSIT = 0 (no MOb), the return value is 0xF.
Note:
• Bit 3:0 – CGP3:0: CAN General Purpose Bits
These bits can be pre-programmed to match with the wanted configuration of the CANPAGE
register (i.e., AINC and INDX2:0 setting).
