It's not surprising with many contradicting papers on the subject, micro datasheets saying "see the crystal manufacturer", crystal documentation saying "as per micro datasheet" and magazine articles devoting 95% to how the manufacturer makes the part. The following paragraphs just touch on each of the most commonly asked questions. Power Debugger is a powerful development tool for debugging and programming AVR microcontrollers using UPDI, JTAG, PDI, debugWIRE, aWire, TPI or SPI target interfaces and ARM® Cortex®-M based SAM microcontrollers using JTAG or SWD target interfaces.

XTAL1, XTAL2 (Crystal Pins) These pins are normally directly connected to the external crystal (1.8432 M Hz) used to derive the various baud rates. Alternatively, an externally generated clock may be used to drive the XTAL1 pin, in which case the XTAL2 pin must float. XTAL1 is the input pin for the transmit clock. TxD (Transmit Data)
