Instructions for Use
Power Supply:
- Ensure the supply voltage (Vcc) is within the specified range of 5.0 V ± 10%.
- Connect a decoupling capacitor (typically 0.1 μF) close to the Vcc pin to stabilize the power supply.
Clock Configuration:
- The microcontroller supports both internal and external clock sources. For external crystal, connect the crystal between the XTAL1 and XTAL2 pins.
- Configure the clock source using the appropriate register settings in your initialization code.
Programming:
- Use a compatible programmer to load the program into the flash memory.
- Ensure the programming voltage (Vpp) is applied correctly if required by the programmer.
I/O Configuration:
- Set the direction of I/O pins using the Data Direction Register (DDR).
- Configure the pull-up resistors and other I/O settings as needed.
Interrupts:
- Enable and configure interrupts using the Interrupt Vector Table (IVT) and the appropriate control registers.
- Write interrupt service routines (ISRs) to handle specific interrupt events.
Low Power Modes:
- Enter low power modes using the appropriate control registers.
- Ensure that the necessary wake-up sources are configured before entering a low power mode.
Communication Interfaces:
- Initialize the SCI, SPI, and I2C modules using the respective control registers.
- Configure baud rates, data formats, and other parameters as required for communication.
Watchdog Timer:
- Enable the watchdog timer if needed for system reliability.
- Service the watchdog timer periodically to prevent a reset.
Analog-to-Digital Conversion:
- Configure the ADC module using the control registers.
- Select the input channel and start the conversion process.
- Read the conversion results from the appropriate data register.
Debugging:
- Use the on-chip debugging features, if available, to monitor and control the microcontroller during development.
- Connect a debugger or emulator to the debug interface pins for real-time monitoring and code execution control.
