11.5. XBUF Output

The XBUF pin can be used to clock a device or a microcontroller. By default the output is enabled with a

frequency of 6.78MHz. The frequency can be doubled to 13.56MHz by setting the bit XBUFSel. When the

output is not used, it is recommended to disable the clock by setting the bit XBUFEnB.
