Migrating from the SPWF01Sx to the SPWF04Sx

We're trying to migrate a board from the SPWF01SC to the SPWF04SC. Two of the additions to the SPWF04 are the LSE and HSE external clock pins. They're not displayed on the block diagram for the SPWF04 in its datasheet so does it use the STM32F429's internal RC oscillator by default or do we need to add oscillators to our board as per the X-NUCLEO-IDW04A1 evaluation board?
