Categories of data in C, like integer, float, and character, affecting how memory is used.

Creating a named storage location in memory with a specified data type.

Fixed values that cannot be changed during program execution.

Symbols performing mathematical operations (+, -, *, /,%).

Specific structures to control the order in which statements are executed.

Executes a block of code only if a condition is true.

Reusable blocks of code that perform specific tasks.

Variables storing memory addresses of other variables.

A collection of elements of the same data type stored in contiguous memory locations.

Data type that groups variables of different data types into a single unit.

Specific pins on AVR Mega microcontrollers that can trigger an interrupt when a change in signal level occurs. These pins are designed for fast response to external events.

A feature on AVR Mega devices that allows interrupts to be generated based on changes in the state of specific input pins. This provides a flexible way to detect pin transitions without constantly polling them.

A special function in a microcontroller program that is automatically executed when an interrupt occurs. The ISR handles the specific event that caused the interrupt and takes appropriate actions.

The Power Management and Interrupt Controller (PMIC) is a component in XMega devices that manages power supply and interrupt requests. It controls power consumption and prioritizes interrupts.

Interrupts in XMega microcontrollers that can be enabled or disabled by software through a specific mask register. This allows for selective interrupt handling.

An interrupt in XMega devices that cannot be disabled by software and has the highest priority. It's typically used for critical events like system failures.

A hierarchical structure in XMega devices that prioritizes interrupts. Different interrupt sources can be assigned to different priority levels, determining the order of execution when multiple interrupts occur.

A numerical value assigned to an interrupt source in XMega devices, representing its priority level. Lower numbers indicate higher priority.

A specific type of interrupt in XMega devices that can be triggered by transitions on a certain PORT pin. This allows for flexible event detection on specific pins.

The Watchdog Timer is a safety feature that prevents your microcontroller from becoming stuck in an infinite loop. It periodically requires a signal to reset its timer, otherwise, it causes a system reset.

A mechanism in the XMega microcontroller that allows different events, like timer overflows or button presses, to trigger specific actions.

Events are occurrences that happen within the microcontroller, such as timer overflows or button presses.

The process of connecting events to specific actions or functions to be executed.

A set of timers within the XMega microcontroller that can be used for various purposes, including creating time delays, generating waveforms, or counting events.

The source of the clock signal used to drive the timer, which can be the main system clock or other internal clock sources.

A timer operating mode that allows the timer to count up or down from a specified value and generate an interrupt when it reaches a specific value.

A timer functionality that allows capturing the precise time (value) when an external signal transitions on a timer input pin.

A special case of input capture where the timer is used to measure the frequency of an external signal.

A special case of input capture used to determine the duration of a pulse signal.

A timer mode used to generate custom waveforms with various frequencies and duty cycles.

A mechanism where a program jumps to a separate block of code called a subroutine, executes it, and then returns to where it left off, improving code organization and reusability.

A development environment designed for AVR microcontrollers, providing tools to write, compile, and debug C programs targeting these microcontrollers.

The main timing signal that drives the AVR microcontroller, determining its operating speed and synchronizing its operations.

A method of data transfer where multiple bits are transferred simultaneously, allowing for faster and more efficient data handling.

Components or circuits that control the amount of current flowing through LEDs, ensuring they are lit at the desired brightness.

Events or signals that cause the AVR microcontroller to temporarily stop its current operations and jump to a specific interrupt service routine (ISR), enabling responsive reactions to external inputs.

Controlling the motion of stepper motors by precisely directing current to their windings, enabling precise and controlled movements.

A technique that allows data transfers between peripherals and memory to occur directly without involving the CPU, freeing up the CPU for other tasks.
