Instructions for Use:

1. Power Supply:

   • Connect the V_CC pin to a stable 5V supply.
   • Ensure the supply voltage is within the specified range (4.5V to 5.5V).

2. Bus Connection:

   • Connect the CAN_H and CAN_L pins to the CAN bus lines.
   • The bus voltage should not exceed 5.5V.

3. Grounding:

   • Connect the GND pin to the system ground.

4. Signal Lines:

   • Connect the TXD and RXD pins to the microcontroller or other communication interface.
   • Ensure proper termination resistors (120Ω) are used on the CAN bus for reliable operation.

5. Configuration:

   • Configure the device using the control registers via the SPI interface.
   • Refer to the datasheet for specific register addresses and bit configurations.

6. Operation:

   • The device operates in either CAN 2.0A (11-bit identifier) or CAN 2.0B (29-bit identifier) mode.
   • Set the appropriate mode in the configuration registers.

7. Error Handling:

   • Monitor error counters and status flags to detect and handle errors.
   • Implement error recovery mechanisms as needed.

8. Temperature Considerations:

   • Ensure the operating temperature is within the specified range (-40°C to 125°C).
   • Monitor the junction temperature to avoid overheating.

9. ESD Protection:

   • Handle the device with care to avoid electrostatic discharge (ESD).
   • Use ESD protection measures during handling and assembly.

10. Testing:

    • Test the device in a controlled environment to ensure it meets the required performance specifications.
    • Verify communication integrity and error handling capabilities.
