A 25 MHz clock source is required to be connected to the high frequency oscillator (MCU_OSC0) for proper operation of the processor.
Select a crystal or 1.8 V LVCMOS square-wave digital clock source. Discrete components used to implement the oscillator circuit are recommended to be placed as close as possible to the MCU_OSC0_XI and MCU_OSC0_XO pins. For the crystal, follow the MCU_OSC0 Crystal Circuit Requirements table of the device-specific data sheet when choosing the load capacitors.
When using 1.8 V LVCMOS square-wave digital clock source terminate the processor XO pin as per the device-specific data sheet recommendation.
