The recommended processor clock inputs and connections are summarized in the Clock Specifications section in the Specifications chapter of the device-specific data sheet.
A 25 MHz external main crystal interface pins connected to the internal high frequency oscillator (MCU_HFOSC0), is the default clock source for internal reference clock HFOSC0_CLKOUT.
Very few applications require WKUP_LFOSC0 and is optional. Based on the use case, select a 32.768 kHz crystal as clock source or 1.8 V LVCMOS square-wave digital clock source. For more information, see the [FAQ] AM625: LFOSC usage in the device. This is a generic FAQ and can also be used for AM623, AM625SIP, AM625-Q1 and AM620-Q1 family of processors.
