19.10.14 CAN Transmit Error Counter Register - CANTEC
19.10.15 CAN Receive Error Counter Register - CANREC
19.10.16 CAN Highest Priority MOb Register - CANHPMOB
19.10.17 CAN Page MOb Register - CANPAGE
7682C–AUTO–04/08
• 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).
• Bit 7:4 – MOBNB3:0: MOb Number
Selection of the MOb number, the available numbers are from 0 to 14.
• Bit 3 – AINC: Auto Increment of the FIFO CAN Data Buffer Index (Active Low)
• Bit 2:0 – INDX2:0: FIFO CAN Data Buffer Index
Byte location of the CAN data byte into the FIFO for the defined MOb.

– 0 - auto increment of the index (default value).
– 1- no auto increment of the index.
Do not confuse “MOb priority” and “Message ID priority”.
