ATXMEGA128A4U-AU Frequently Asked Questions (FAQs)
What is the maximum clock frequency that can be used with the ATXMEGA128A4U-AU?
The maximum clock frequency is 32 MHz, but it can be overclocked to 40 MHz with some limitations.
How do I configure the clock source for the ATXMEGA128A4U-AU?
The clock source can be configured using the CLKCTRL (Clock Control) register. The internal RC oscillator can be used as the clock source, or an external clock source can be used by connecting it to the XTAL1 pin.
What is the maximum amount of current that can be sourced or sunk by the GPIO pins?
The maximum current that can be sourced or sunk by the GPIO pins is 20mA per pin, with a total current limit of 200mA for all pins combined.
How do I use the built-in UART on the ATXMEGA128A4U-AU?
The UART can be configured using the USART (Universal Synchronous Asynchronous Receiver Transmitter) module. The USART module can be used in asynchronous mode for UART communication, and can also be used in synchronous mode for SPI communication.
What is the purpose of the JTAG interface on the ATXMEGA128A4U-AU?
The JTAG (Joint Test Action Group) interface is used for debugging and programming the device. It allows for boundary scan testing, debugging, and programming of the device using a JTAG interface.
