Instructions for Using AT90CAN128-16AU

1. Power Supply:

   • Ensure the supply voltage is within the range of 2.7V to 5.5V.
   • Use a stable power source to avoid voltage fluctuations that can cause system instability.

2. Clock Configuration:

   • The device supports both internal and external clock sources. For external clock sources, connect a crystal or oscillator to the XTAL1 and XTAL2 pins.
   • Set the fuse bits to configure the clock source as required.

3. Programming:

   • Use an ISP programmer to program the flash memory. Connect the programmer to the ISP header (MISO, MOSI, SCK, RESET, VCC, GND).
   • Ensure the programming software is compatible with the AT90CAN128-16AU.

4. CAN Interface:

   • Initialize the CAN controller using the appropriate registers.
   • Configure the bit timing parameters for the desired baud rate.
   • Use the CAN interrupts to handle message reception and transmission.

5. ADC Configuration:

   • Select the ADC channel and set the reference voltage.
   • Start the conversion by setting the appropriate bits in the ADC control register.
   • Read the conversion result from the ADC data register.

6. Timers and PWM:

   • Configure the timer prescaler and mode of operation.
   • Set the compare match values for generating PWM signals.
   • Enable the PWM output on the designated pins.

7. USART Configuration:

   • Set the baud rate, data frame format, and enable the USART module.
   • Use the transmit and receive buffers to send and receive data.

8. SPI and TWI:

   • Configure the SPI or TWI module as master or slave.
   • Set the clock speed and data format.
   • Use the appropriate registers to transfer data.

9. Interrupts:

   • Enable the required interrupts in the interrupt mask register.
   • Write the interrupt service routines (ISRs) to handle the interrupts.

10. Sleep Modes:

    • Enter sleep modes to reduce power consumption.
    • Use the sleep mode control register to select the appropriate mode.
    • Wake up the device using external interrupts or watchdog timer.

11. Pin Configuration:

    • Configure the I/O pins as input or output using the DDR (Data Direction Register) and PORT registers.
    • Use pull-up resistors for input pins if necessary.

12. Debugging:

    • Use the debugWIRE interface for on-chip debugging.
    • Connect a debugger to the debugWIRE pin and use the appropriate software tools.

By following these instructions, you can effectively utilize the AT90CAN128-16AU microcontroller in your applications.
