| CFRXIE | Common FIFO RX Interrupt Enable 0 (0): FIFO interrupt generation disabled for Frame RX 1 (1): FIFO interrupt generation enabled for Frame RX |
| CFTXIE | Common FIFO TX Interrupt Enable 0 (0): FIFO interrupt generation disabled for Frame TX 1 (1): FIFO interrupt generation enabled for Frame TX |
| CFPLS | Common FIFO Payload Data Size Configuration 0 (000): 8 bytes 1 (001): 12 bytes 2 (010): 16 bytes 3 (011): 20 bytes 4 (100): 24 bytes 5 (101): 32 bytes 6 (110): 48 bytes 7 (111): 64 bytes |
| CFM | Common FIFO Mode 0 (00): RX FIFO mode 1 (01): TX FIFO mode 2 (10): CAN – CAN GW FIFO mode 3 (11): Reserved |
| CFITSS | Common FIFO Interval Timer Source Select 0 (0): Reference clock (× 1 / × 10 period) 1 (1): Bit time clock of related channel (FIFO is linked to fixed channel) |
| CFITR | Common FIFO Interval Timer Resolution 0 (0): Reference clock period × 1 1 (1): Reference clock period × 10 |
| CFIM | Common FIFO Interrupt Mode 0 (0): RX FIFO mode: RX interrupt generated when Common FIFO counter reaches CFIGCV value from a lower value TX FIFO mode: TX interrupt generated when Common FIFO transmits the last message successfully GW FIFO mode: For RX interrupt flag: Interrupt generated when FIFO counter increments and reaches the value configured in CFIGCV For TX interrupt flag: Interrupt generated when FIFO transmits the last message successfully 1 (1): RX FIFO mode: RX interrupt generated at the end of every received message storage TX FIFO mode: interrupt generated for every successfully transmitted message GW FIFO mode: For RX interrupt flag: Interrupt generated when a message is stored in the FIFO For TX interrupt flag: Interrupt generated when a message is successfully transmitted from the FIFO |
| CFIGCV | Common FIFO Interrupt Generation Counter Value 0 (000): Interrupt generated when FIFO is 1/8th full 1 (001): Interrupt generated when FIFO is 1/4th full 2 (010): Interrupt generated when FIFO is 3/8th full 3 (011): Interrupt generated when FIFO is 1/2 full 4 (100): Interrupt generated when FIFO is 5/8th full 5 (101): Interrupt generated when FIFO is 3/4th full 6 (110): Interrupt generated when FIFO is 7/8th full 7 (111): Interrupt generated when FIFO is full |
