7.1.1 27.12 MHz Crystal oscillator (XTAL)

The 27.12 MHz crystal oscillator is used as a reference for all operations requiring high
stability of the clock frequency. This includes: contactless interface, contact interface, SPI
and I2C master interfaces, HSUART and USB PLL for the USB interface.

To ensure the stability of the clock frequency, it is recommended to adopt the circuit with
the external quartz and the trimming capacitors shown in

summarizes

the requirements for the crystals.

7.1.1.1 XTAL activation sequence

The XTAL is automatically activated by the digital control unit as soon as the system
reset is released. The LFO needs to be activated to start the XTAL Oscillator.
