19.1 CAN Module-Related Registers
The CANi (i = 0, 1) module has the following registers.
19.1.1 CANi Message Box (i = 0, 1)
19.1.2 Acceptance Mask Registers
19.1.3 CAN SFR Registers
Explanation of each register is given below.
A CAN module is equipped with 16 slots (16 bytes or 8 words each). Slots 14 and 15 can be used as
Basic CAN.
• Priority of the slots: The smaller the number of the slot, the higher the priority, in both transmission and
• A program can define whether a slot is defined as transmitter or receiver.
A CAN module is equipped with 3 masks for the acceptance filter.
• CANi global mask register (i = 0, 1) (CiGMR register: 6 bytes)
• CANi local mask A register (CiLMAR register: 6 bytes)
• CANi local mask B register (CiLMBR register: 6 bytes)
• CANi message control register j (i = 0, 1, j = 0 to 15) (CiMCTLj register: 8 bits ✕ 16)
• CANi control register (CiCTLR register: 16 bits)
• CANi status register (CiSTR register: 16 bits)
• CANi slot status register (CiSSTR register: 16 bits)
• CANi interrupt control register (CiICR register: 16 bits)
• CANi extended ID register (CiIDR register: 16 bits)
• CANi configuration register (CiCONR register: 16 bits)
• CANi receive error count register (CiRECR register: 8 bits)
• CANi transmit error count register (CiTECR register: 8 bits)
• CANi time stamp register (CiTSR register: 16 bits)
• CANi acceptance filter support register (CiAFS register: 16 bits)
reception.
Configuration of the masking condition for acceptance filtering processing to slots 0 to 13
Configuration of the masking condition for acceptance filtering processing to slot 14
Configuration of the masking condition for acceptance filtering processing to slot 15
Control of transmission and reception of a corresponding slot
Control of the CAN protocol
Indication of the protocol status
Indication of the status of contents of each slot
Selection of “interrupt enabled or disabled” for each slot
Selection of ID format (standard or extended) for each slot
Configuration of the bus timing
Indication of the error status of the CAN module in reception: the counter value is incremented or
decremented according to the error occurrence.
Indication of the error status of the CAN module in transmission: the counter value is incremented or
decremented according to the error occurrence.
Indication of the value of the time stamp counter
Decoding the received ID for use by the acceptance filter support unit
