8209D–AVR–11/10
• Bits 15:0 - CANTIM[15:0]: CAN Timer Count
CAN timer counter range 0 to 65,535.
• Bits 15:0 - TIMTTC[15:0]: TTC Timer Count
CAN TTC timer counter range 0 to 65,535.
• Bit 7:0 – TEC[7:0]: Transmit Error Count
CAN transmit error counter range 0 to 255.
• Bit 7:0 – REC[7:0]: Receive Error Count
CAN receive error counter range 0 to 255.
• Bit 7:4 – HPMOB[3:0]: Highest Priority MOb Number
MOb having the highest priority in CANSIT registers.
If CANSIT = 0 (no MOb), the return value is 0xF.
